An 1870s Study of Pre-Historic Man in Whiteside County, Illinois.


In historical writing and analysis, PRESENTISM introduces present-day ideas and perspectives into depictions or interpretations of the past. Presentism is a form of cultural bias that creates a distorted understanding of the subject matter. Reading modern notions of morality into the past is committing the error of presentism. Historical accounts are written by people and can be slanted, so I try my hardest to present fact-based and well-researched articles.

Facts don't require one's approval or acceptance.

I present [PG-13] articles without regard to race, color, political party, or religious beliefs, including Atheism, national origin, citizenship status, gender, LGBTQ+ status, disability, military status, or educational level. What I present are facts — NOT Alternative Facts — about the subject. You won't find articles or readers' comments that spread rumors, lies, hateful statements, and people instigating arguments or fights.

FOR HISTORICAL CLARITY
When I write about the INDIGENOUS PEOPLE, I follow this historical terminology:
  • The use of old commonly used terms, disrespectful today, i.e., REDMAN or REDMEN, SAVAGES, and HALF-BREED are explained in this article.
Writing about AFRICAN-AMERICAN history, I follow these race terms:
  • "NEGRO" was the term used until the mid-1960s.
  • "BLACK" started being used in the mid-1960s.
  • "AFRICAN-AMERICAN" [Afro-American] began usage in the late 1980s.

— PLEASE PRACTICE HISTORICISM 
THE INTERPRETATION OF THE PAST IN ITS OWN CONTEXT.
 


When Europeans first penetrated the country beyond the Appalachian Mountains, they found it covered with dense forests and presented no evidence of ever having been cultivated. Still, here and there were hillocks (a hill or mound) of regular form, some of them of great size, usually occupying commanding positions on the highlands overlooking streams. Besides these hillocks, evidently the work of man, there were walls of great extent, some of them enclosing tracts of many acres, in several cases of more than 100 acres in area. Of these works, the Indians living in the country at that time could give no account whatsoever but a vague and unsatisfactory one. Research has resulted only in theories and conjectures, often of the wildest and most improbable character.
One of the larger-sized mounds (Site 7) was found at the Sinnissippi Site in Sterling, Illinois.

The word "Mississippi" comes from the Ojibwe Indian Tribe (Algonquian language family) word "Messipi" or "misi-ziibi," which means "Great River" or "Gathering of Waters." French explorers, hearing the Ojibwe word for the river, recorded it in their own language with a similar pronunciation. The Potawatomi (Algonquian language family) pronounced "Mississippi" as the French said it, "Sinnissippi," which was given the meaning "Rocky Waters."

In Sterling, Whiteside County, Illinois, many mounds are found. Three or four are placed on the high point southwest of Albany, commanding a fine view of the Mississippi in both directions. They appear to contain only bones, which crumble as soon as exhumed. Several were in Fenton, on the slope overlooking the Rock River Bottom. In Como, a number are found. Some of these have been examined (in the 1870s), and fragments of bone were discovered. In Carroll County, Mr. J.M. Williamson found a vast collection of flint chippings, the material of several varieties as if brought from different localities, which are believed to mark the site of an arrow and spearhead production.

The articles found in mounds are of considerable variety, embracing arrow and spearheads, stone axes, shaped and pierced fragments of stone, intended either for ornament or as charms, earthenware coarse and unglazed but usually ornamented with simple designs, earthen vessels of various sizes and forms, beads, etc. Some pieces of copper and other minerals foreign to the locality and evidently esteemed for their beauty and rarity have been obtained. In a few instances, stone tablets have been unearthed and covered with hieroglyphic characters [1], which seem to be designed as a sort of record from their grouping and arrangement.

Most of the mounds were undeniably tombs, as they contain only bones and such articles as were buried with the dead; others contain nothing and seem to have been designed as places for lookouts, while others, no doubt, were at one time places at which religious exercises were held and where sacrifices were offered, and these we have reason to believe were often of human beings.

Are all the mounds the same age? Certainly not. Assuming that all of the buildings in Whiteside County were erected in the same year, then building ceased.

Were the builders the ancestors of the present Indians? There is nothing to prove that they were not; some facts show they were. 

If skeletons are of any value as evidence, then we must admit that there is a good reason for assuming those ancient builders and the present Indians to be of the same race. It's doubtful if a mound 2,000 years old exists in the United States. Seeking an age much greater than 4500 years old defies common sense because the earliest known Egyptian pyramid (at Saqqara, Egypt, the Step Pyramid of Djoser) was built around 2630 BC. Investigators, unfortunately, generally construct a theory and then search for facts to prove it, viewing each fact captured through the microscope of prejudice and prepossession, and, of course, succeed in getting at everything but the truth.

The flint implements, arrowheads and spearheads that have been discovered are of various grades of workmanship, some highly finished and others rough and clumsy. The material differs from a fine semi-translucent horn stone to a dull oolitic chert of two or more shades of color.

The earthenware is of various colors, some almost a cream tint through all shades to a dark brown. It is generally rough, coarse, as to material, thick, clumsy in form, and ornamented in geometrical designs of straight parallel lines, either of one or two series. Some specimens are, however, of a higher type, of fine form, and skillfully modeled.

The beads are generally of bone or stone. They are of irregular forms, of various sizes and were probably worn for ornament. Circular and triangular pieces of stone pierced with one or more holes seem to have been intended for the same purpose but may have been used as amulets or charms. They do not appear to have been numerous. The pieces of copper found in these tombs were probably collected from the drift, but that at one time and for a considerable length of time, it was mined on Lake Superior cannot be doubted, and it may have been an article of traffic among these people. Masses of it weighing several pounds have, however, been obtained in the drift of the Illinois River and the Rock River.

W.C. Holbrook, Esq., of Genesee, who has thoroughly investigated the labors of the mound builders in Whiteside County, presents his conclusions and observations as follows:
There are fifty-one mounds near Albany; a large number in the vicinity of Como. He has examined four mounds and two altars in Clyde. Several groups of mounds and earthworks are to be seen on Rock River above Sterling. Below the Sterling fairgrounds are twenty-two mounds, one of which is the largest in the county. The Albany mounds are rounded heaps of loose sandy soil, from two to twelve feet in height, usually circular, of a diameter five times the height. Several of the mounds are elliptical, their long diameter parallel with the river. In these mounds have been found galena, mica and fragments of pottery, the pottery bearing the impression of some kind of woven or matted fabric, bone implements and various portions of human skeletons.
Using a comparative table of the length of long bones, Dr. Farquharson of Davenport, Iowa, found that none belonged to a person taller than six feet. In May 1877, Mr. Holbrook examined several mounds north of the Catholic Cemetery in the vicinity of Sterling, one of which was a large mound, one of a number in a row parallel with the river. On moving the clay, it was found that this mound contained a Dolmen [2] built of flat pieces of fossiliferous limestone. The stones used were quite large. The wall was a right-angled parallelogram, twelve feet long and five wide; the foundation was laid upon clay, and the wall was built artistically, with no cement. The inner surface was smooth and even, although the stones were unhewn. The inside of the Dolmen revealed fragments of eight skeletons, the bones badly decomposed. Apparently, the bodies were cast into the sepulcher (a small room or monument, cut in rock or built of stone, in which a dead person is laid or buried ) promiscuously. The skulls found indicated that these people were acquainted with the division of surgery known as "trepanning" (removing portions of the bones of the skull or portions of other bones). A thigh bone that had been fractured was found replaced and united in a manner that would do honor to a surgeon of the present day. The skulls were found to plummet, fossils not found in this locality, finely black polished pebbles, and several large teeth. In another mound was found an altar of burned rock, oval in shape, long diameter of six feet, and short diameter of four and a half feet. The altar was of fossiliferous limestone. Over the mounds were found one to ten feet of vegetable growth and a decayed stump of a hickory tree, about twelve inches in diameter. On and about the altars were usually found charcoal and charred remains of human beings, also evidence of great and continued heat.

At Sterling, the indications are that the body was placed upon the clay, covered with black loam [3], and a great fire built over the whole. After the fire, the mound was raised. This is indicated by the thick strata of charcoal and ashes found. As a rule, the remains unearthed furnish unsatisfactory evidence. Significant numbers of perfect molar teeth are exhumed, thus certifying that pre-historic man was unacquainted with the sharp pain of a toothache. Stone scrapers were found in the Sterling mounds but were very rude in design and execution. Fragments of pottery were found, as well as implements made from the antlers of the elk and deer. 

At Sterling is a work that many call a fortress. The two embankments are parallel, 66 feet apart, in an east/west direction. The south embankment has two gateways. The north embankment is 264 feet long and has two gateways. The construction indicates a knowledge of the cardinal points of the compass (North, South, East and West). These people evidently had a practical acquaintance of astronomy, as the north star appears to have been a governing point with them.

The Mound Builders wore cloth and dressed in the hides of animals, carved rude ornaments and engraved characters upon the stone, ate food from earthen dishes, and worshiped at altars erected upon high hills and in low valleys. There are abundant reasons for believing that human sacrifice was common to them. Trepanned skulls (a form of surgery that involves boring holes through a person's skull) are frequently met with on-opening mounds, evidence being presented that the operation was made before death. The superstition of the Mound Builders seems analogous (performing a similar function but having a different evolutionary origin, such as the wings of insects and birds) to that of the South Sea Islanders and tribes of savages of the 18th & 19th centuries who trepan for vertigo, neuralgia (a stabbing, burning, and often severe pain due to an irritated or damaged nerve), etc., believing that these complaints are demons in the head that should be let out.

Copper was the king of metals among the Mound Builders, and metal was worked on imperfectly.

Anatomically considered, the Mound Builders were no larger nor stronger than the men of the 18th & 19th centuries. Their skulls differ widely from the Indian or Caucasian and have been thus described as: 
"The frontal bone recedes backward from a prominent superciliary ridge, leaving no forehead, or rather the eye looks out from under the frontal plate, very similar to a turtle shell, and no more elevated." 
Their jaws were protruding, prominent and wide. The evidence is that the Mound Builders were half-civilized agricultural people, prominently differing from the Indians in the manner of burial and habits of life. The scientifically developed fact that bones undergo great changes by age, as applied by Dr. Farquharson and Mr. Holbrook, proves the great antiquity of the bones found in the mounds of this county.

About the Stone Age of Whiteside County, Mr. Holbrook says that stone implements are occasionally found in all parts of the county. The number of implements found in some localities indicates that primitive men lived in villages, and each village had at least one arrow maker. The men of the Stone Age evidently admired the beautiful and sublime in nature, for the sites of their ancient villages are in the county's most picturesque and grand localities. In one of these villages in the southwestern part of Genesee, eighty-four arrowheads and spear points were found while plowing an acre of ground. Several small, sharp, triangular flint pieces that had perhaps been used for the "teeth" of war clubs were also found. In another village, on Mr. Deyo's farm in Clyde, we find the number of domestic implements to be greatly greater than that of the weapons. More than one hundred scrapers, stone hoes, corn pestles, and some implements of doubtful or unknown uses have been found here. Mr. Deyo plowed up about twenty scrapers that had been carefully buried near the roots of a large white oak; only a small portion of the decayed stump of the once venerable oak now remains. Some of the scrapers found in this "nest" are very interesting because they are half-finished and reveal the method of their manufacture. 
Various stone arrowheads, scrapers, ax heads and other tools are found in Illinois.
The implement maker -- for some were undoubtedly devoted to that business -- found or broke from some larger piece of flint or hornstone, a flat piece of rock; he then began to break off small flakes near the edges on one side, finishing it before he began to chip off the other side; when finished, these scrapers were oval in form, about four inches long and two and one-half broad, one side convex resembling in shape a turtle shell, the opposite side nearly flat or slightly concave. Stone hoes resemble the scraper in form; they are longer and less oval, with an edge upon one end instead of the side and the end opposite the edge smooth for the hand; they had no handles. Pestles for crushing corn are about eight inches long and two inches in diameter. Fish spears are sometimes found among the pebbles in the bottoms of the smaller streams; unfortunately, many of these specimens are broken, so it is not easy to determine their prevailing form. Broken arrowheads and spear points are sometimes found. Arrowheads have been found once broken and chipped into specimens of different forms; others bear evidence of having been broken at the point and repaired afterward. Implements for dressing hides have been found; a good specimen of this class of implements was found by J. M.Williamson in Ustick; it is a small oval boulder about eight inches in diameter and two inches thick; on one side, there is a flat and a very smooth polished surface. The materials from which the implements of the Stone Age are manufactured are all found in the drift of Whiteside County. There are, however, several exceptions: a pipe of the Minnesota pipe-stone has been found in Genesee, and a spearhead of a peculiar quality of quartzite found at Devil's Lake, Wisconsin, has been picked up in Clyde. Arrowheads were made from almost every variety of horn-stone; a few were made of milky quartz, and one in the collection of J. M. Williamson is pure yellow jasper. Stone axes weighing from four ounces to thirteen pounds have been found. An ax in Mr. Holbrook's collection weighs eleven pounds and is unfinished. Large quantities of flint chippings are found in some localities; they prove that the arrow-makers understood the conchoidal fracture and planes of cleavage of the materials used. Some specimens are rude and imperfect, others are perfect and exhibit great skill; some appear very ancient, for their surfaces are weathered or corroded by the tooth of time.

Conclusion
I find that the assumptions made and, thus, some misinformation from this 1877 account of a pre-historic man in Whiteside County have been mostly corrected in the 21st century. Most rough-looking arrowheads, spearheads, and tools were from youth or the inexperienced learning the trade and were tossed into piles as unusable.

Archaeologists theorize that the bird of prey on the front of the tablet symbolically represents the Upper World. The Middle World (of man) is represented by the human figure wearing the costume, and the Lower World is defined by the snakeskin pattern on the back of the tablet.

The Ramey Tablet was also found on site. The tablet was found east of Monks Mound on the Ramey farm sometime during the 19th century. It dates to around 1250 AD. The Ramey tablet is broken in quarters. Only one-half of the tablet was found. The original Ramey tablet is in the Madison County Historical Museum collection in Edwardsville, Illinois.

The Ramey Tablet displays war symbols of the Southeastern Ceremonial Complex with human heads, hair buns, beaded forelocks, ear spools, and pileated woodpeckers.
[2] A dolmen (or cromlech) is a type of single-chamber megalithic tomb, usually consisting of two or more vertical megaliths supporting a large, flat horizontal capstone or "table." Most date from the early Neolithic (4000–3000 BC) and were sometimes covered with earth or smaller stones to form a mound of earth and stones raised over a grave or graves.

[3] Many people confuse loam soil with topsoil, but the truth is that there is a difference between the two.

"Topsoil" refers to any kind of soil that is on top. What you are walking on, riding your bike on, or turning with your shovel is known as topsoil. Topsoil is basically different kinds of organic matter that has decayed with time. There are all kinds of organic matter, like decayed food, grass, rocks, and dirt, so it is usually a bit darker than the soil beneath it.

Loam refers to a unique mixture of sand, clay, and silt. Loam is usually made of half sand, one-quarter silt, and clay. It is considered the best topsoil, as it allows enough water to be soaked into the ground to keep plants hydrated – yet it still drains well enough that air can circulate.

So, the difference between loam soil and topsoil is the exact difference between your thumb and fingers: all loam is a kind of topsoil, but not all topsoil is a kind of loam.

The History of Cahokia's Five Woodhenges.

The Cahokia Woodhenge was a series of large timbers forming a circle located roughly one-half mile west of Monks Mound in the Indian Village of Cahokia site (Collinsville, Illinois, today).
An Illustration of the Cahokia Woodhenge.
They are thought to have been constructed between 900 and 1100 AD, each being larger and having more posts than its predecessor. The site was discovered as part of salvage archaeology in the early 1960s interstate highway construction boom, and one of the circles was reconstructed in the 1980s. The circle has been used to investigate archaeoastronomy at Cahokia Mounds. Annual equinox and solstice sunrise observation events are held at the site.

DISCOVERY AND EXCAVATION
The series of woodhenges at Cahokia was discovered during salvage archaeology undertaken by Dr. Warren Wittry in the early 1960s in preparation for a proposed highway interchange. Although most of the site contained village house features, several unusually shaped large post holes were also discovered. The post holes were 7 feet in length and 2 feet in width, and sloping ramps were formed to accommodate the insertion and raising of the estimated 20-foot tall posts to a 4-foot depth into the ground. When the holes were plotted out, it was realized that they formed several arcs of equally spaced holes. Detailed analytical work supported the hypothesis that the placement of these posts was by design. Wittry hypothesized that the arcs could be whole circles and that the site was possibly a calendar for tracking solar events such as solstice and equinoxes. He began referring to the circles as "woodhenges," comparing the structures to England's well-known circles at Woodhenge and Stonehenge.
Woodhenge lies west of Monks Mound, at the lower-left edge of the illustration.
Dr. Robert L. Hall undertook additional excavations at the site in 1963. Hall used the predicted locations from the arcs found in the previous excavation and found more post holes and posts near the centers of the circles now thought to be central observation points. Wittry undertook another series of excavations at the site in the late 1970s and confirmed the existence of five separate timber circles in the vicinity. The circles are now designated "Woodhenges 1 through 5." Each was a different diameter and had a different number of posts. Because four of the circles overlap, it's thought they were built in a sequence, with each iteration generally becoming more extreme and containing twelve more posts than its predecessor.

The remains of several posts were discovered in the post pits. The type of wood used, red cedar (Juniperus virginiana), is considered sacred by many Native American groups. The red cedar is the only native evergreen species in the area and is resistant to disease and decay. Traces of red ochre pigment were also found, suggesting that the posts were probably painted at some point. In 1985, William R. Iseminger led a series of excavations to see an entire circular sequence of posts. He completed the sequence for what has become known as Woodhenge 3 (except for nine posts on the western edge that had been lost to dump trucks for road construction fill) and then led the circle reconstruction. The reconstruction team obtained enough red cedar logs for half of the holes. Then, it made do with black locust (Robinia pseudoacacia) for the other half, placing them into the originally excavated postpositions. The Illinois Historic Preservation Division (Illinois Department of Natural Resources) oversees the Cahokia site. It hosts public sunrise observations at the vernal and autumnal equinoxes and the winter and summer solstices. Out of respect for Native American beliefs, these events do not feature ceremonies or rituals.

CONSTRUCTION SEQUENCE
The structure was rebuilt several times during the city center's roughly 300-year Woodhenge history. The presence of single-set posthole houses and midden [1] deposits suggests the area was habitation during the early Emergent Mississippian period before the timber circles were constructed. A separate layer of later Mississippian wall trench houses suggests it became a habitation area again after the final woodhenge was no longer used.
Woodhenge 1 was located to the east of the other circles, the only one not built on the same spot as the other four. It had 24 posts and was 240 feet in diameter. This circle was dismantled and at a later date Mound 44 was constructed, partially covering this location.

Woodhenge 2 was constructed to the west of the previous circle. It had 36 posts and was 408 feet in diameter.

Woodhenge 3 had 48 posts and was 410 feet in diameter. It is thought to have been constructed in approximately 1000 AD. This version of the woodhenge was reconstructed in 1985 using the original holes found during excavations. The 48 posts of the circle are set at 7° 30′ apart as measured from the geometric center of the circle, although the central post of the circle is offset from the true center by 5.6 feet to the east. This facilitates the alignment with perimeter posts marking the winter and summer solstice sunrise positions, correcting for the latitude of Cahokias location.

Woodhenge 4 had 60 posts and was 476 feet in diameter.

Woodhenge 5 had an arc and post spacing that suggests it was 446 feet in diameter and could have had 72 posts, although only 13 posts were found in a short arc facing the direction of the sunrise. Archaeologists suspect it may not have been a full timber circle and that by this time the large trees needed for the posts may have been getting scarce in the vicinity of Cahokia.
ALIGNMENTS
Archaeologists think the woodhenge is a solar calendar capable of marking equinox and solstice sunrises and sunsets for the timing of the agricultural cycle and religious observances. During the equinoxes, the sun rises due east of the timber circle. From the vantage point of the circle's center, it appears as if the sun is emerging from the front of Monks Mound, roughly a half-mile away. One of the reasons for the changing position and size of the timber circles may have been the growing size of the Monks Mound as additional layers of earth raised its height and increased its geographic footprint and the desire to keep this symbolic emergence and alignment intact.

The winter solstice sunrise pole is aligned with the Fox Mound (Mound 60, a rectangular platform mound paired with a conical burial mound, Mound 59), which sits across the grand plaza 1,640 feet south of Monks Mound. The top of the roughly 46-foot tall mound projects above the horizon, and back in Cahokian times, it would have had a large temple structure at its summit, raising it even higher. From the central pole of Woodhenge 3, the sun would have appeared to rise from this mound and temple at the winter solstice. Besides their celestial marking functions, the woodhenges also carried religious and ritual meaning reflected in their stylized depiction as a cross-in-circle motif on ceremonial beakers.

One prominent example has markers added to the winter sunrise and sunset positions and was found in an offertory pit near the winter solstice post pit. It also had radiating lines that symbolized the rays of the sun.

As there are many more posts than are necessary for these simple alignments, some archaeoastronomers have speculated that they were also used to observe other celestial events, such as lunar cycles, the motion of the Pleiades star cluster [2], or other stars and planets;. In contrast, others have suggested they were used to align mound and causeway construction projects.

CAHOKIA'S MOUND 72 WOODHENGE
Archaeologist Marvin Fowler has speculated that the woodhenges also served as "aligners" and that there may have been as many as three more in other strategic locations around Cahokia, built to triangulate and layout construction projects. Fowler has put forward at least one other possible circle at Cahokia, but his suggestion has not yet gained full acceptance from other archaeologists.

This location was discovered near Mounds 72 and 96, directly south of Monks Mound. Several post holes may have been a ceremonial area with 412 feet in diameter circle and 48 posts. Archaeologists have dated the placement of at least one of the posts to approximately 950 AD.
Solstice and equinox markers at the Mound "Md" 72 Woodhenge, with the hypothesized full circle of posts.
Archaeological research has shown that four posts were at the cardinal locations of north, south, east, and west, with eastern and western posts marking the equinox sunrise and sunset positions. Four other posts in the circle were shown to be at the summer solstice sunrise and sunset and the winter solstice sunrise and sunset positions. This setup is nearly identical to the diameter and post positions of Woodhenge 3, differing only in that Woodhenge 3 was 2 feet smaller in diameter. The placement of the two mounds at the location and the directions they are oriented correspond to several of the solstice marking posts. The post nearest the later elite burial spot of the "Birdman" is the location that marked the summer solstice sunrise at the time of the site's use. The early stages of the mounds were actually constructed around the posts, although at a later point, the posts were removed.

The Birdman tablet was discovered in 1971 during excavations at the base of the eastern side of Monks Mound conducted by the University of Wisconsin at Milwaukee.

Female Skeletons Identified as Nobles found in Cahokia's 'Beaded Burial' Mound 72.

From about 800 to 1350 AD, Cahokia was apparently one of the biggest cities in the world. At its height, it had 20,000 residents. The complex society at Cahokia, part of the Mississippian Culture, prospered in the fertile lands off of the Mississippi Valley across the river from modern St. Louis, Missouri.
In the ruins of the ancient city of Cahokia, which flourished hundreds of years ago, there is a burial mound with the remains of a royal or noble couple. Buried around them in the mound are the skeletons of many people who were brutally chopped up, strangled or bled to death in apparent sacrifices.

Burial Mound 72 is called the “beaded burial” because two of the bodies at the center of the grave contained two bodies on a bed of luxurious beads, but it was previously thought to contain the bodies of six highly important men. A new study concludes that some of the 12—not six—high-status skeletons include women and one child. Buried at the very center of this central beaded burial feature is the couple—that is, a man and woman. The burial mound was used from about 1000 to 1200 AD.

“The fact that these high-status burials included women changes the meaning of the beaded burial feature,” archaeologist Thomas Emerson of the Illinois State Archaeological Survey said. “Now, we realize, we don’t have a system in which males are these dominant figures and females are playing bit parts. And so, what we have at Cahokia is very much a nobility. It’s not a male nobility. It’s males and females, and their relationships are very important.”

Inside the burial mound, rediscovered in 1967 by archaeologist Melvin Fowler, were five mass graves with between 20 to more than 50 bodies. Many of them were sacrificed.
This graphic shows the arrangement of the beaded burial, which had a man and woman, not just two men as was previously believed.
Mound 72 burials are some of the most significant burials ever excavated in North America from this time period. Fowler’s and others’ interpretation of these mounds became the model that everybody was looking at in terms of understanding status and gender roles and symbolism among the indigenous people groups in the 1960s era.

Recent research says that Fowler and other researchers erroneously concluded the beaded burial was of two high-status men who were buried with their servants. They thought the beaded cape or blanket was in the shape of a bird, which are symbolic to warrior societies and mythology in the Indian culture. So Fowler concluded that the beaded burial was of two male warrior chiefs. Researchers extrapolated these conclusions to surmise that Cahokia had a “male-dominated hierarchy.”

A fresh look at the early archaeologists’ maps, notes and reports, and the skeletal remains told a new and surprising story. First, the researchers found that there were 12 bodies associated with the beaded burial – not six, as had been previously reported. And independent skeletal analyses revealed that the two central bodies in the beaded burial were actually male and female. Further analyses revealed other male-female pairs on top of, and near, the beaded area. Some were laid out as fully articulated bodies. Others were disarticulated bodies, the bones of which had been gathered and bundled for burial near these important couples. The researchers also discovered the remains of a child.
Mound 72 at Cahokia held several mass graves but also burials of high-status individuals, some of which included items like these artifacts. Pictured here are chunky stones likely used in games, Cahokia-style tri-notched projectile points, and marine shell disc beads like those used in the beaded burial at Cahokia.
Researchers had speculated that victims of human sacrifice found at Cahokia were brought in from outside the area, perhaps as a tribute. But an analysis of the element strontium (is a trace element found in seawater and soil and is similar to calcium, with the symbol Sr and atomic number 38, its an alkaline earth metal) in the victims’ teeth shows they were mainly local -- especially the 39 people brutally killed and unceremoniously dumped in a mass grave.

Strontium is absorbed into the human body from the underlying bedrock through the consumption of local animals and plants. Since the levels of strontium vary across the midcontinent depending on the local geology the level of strontium absorbed by individuals also varies. Investigations of the strontium levels of the remains of individuals who died at Cahokia between 900 AD and 1350 AD indicate that fully one-third of these people were foreigners from outside the immediate vicinity of Cahokia. This suggests that Cahokia could not rely on traditional kin-based political and social models but likely had to “invent” new ways of social and political control and population management.

Mound 72 had groups of people, some of the victims of sacrifice, buried in large pits. Many were laid out in neat rows and had little sign of trauma. Researchers speculate they died of strangulation or blood-letting.

Did Megafloods spell the end of the Ancient City of Cahokia?

The mysterious demise of the ancient city of Cahokia has long remained unexplained. Still, recent research suggests catastrophic megafloods may have devastated crops and food stores and forced residents to suddenly abandon their city some 700 years ago.

Once North America's largest and most sophisticated cultural center north of Mexico, the ancient city of Cahokia, located in present-day Southern Illinois, was an economic powerhouse at its height from about 1000 to 1150 AD. Its sphere of political and religious influence extended from the Great Lakes to the Gulf of Mexico. The city was home to approximately 20,000 people, and it sprawled over 6 square miles, boasting 120 man-made mounds — the largest of which was 10 stories or 100 feet in height, and its footprint covered 14 acres or 610,000 square feet. Known as Monks Mound, it was the largest prehistoric earthwork in the Americas. The building of the mound was a massive undertaking, requiring an estimated 79,000 square feet of earth. 

Samuel Munoz, a geographer at the University of Wisconsin-Madison, has spent several years researching how Cahokia's residents shaped the local landscape, such as how farming affected the region. During this research, he discovered the buried remains of a massive flood dated that likely destroyed the crops and houses of more than 15,000 people. Evidence for the flood is a silty deep core sediment layer nearly 8 inches thick, dated to 1200 AD, +/- 80 years. Although Cahokia wasn't completely abandoned until 1350 AD, Munoz had been able to show that the area experienced periods of severe flooding as the climate changed over the centuries. The catastrophic flood would have shaken the city's confidence, eventually leading them to decide to move on, and the inhabitants never returned.

Beginning of the End
The exact reasons behind the city's decline have long been debated by scientists. Various theories include political battles, crop failures, climate change, and an epic fire. However, Munoz and colleagues established the timing and severity of the historical flood patterns in the area.

Cahokia's decline coincided with a major Mississippi River surge around 1200 AD. The sediment core samples contained almost no charcoal, pollen, or plant matter fossils and were made of silty clay, much like floodwater sediments. This indicated a period of flooding. However, the layers above and below the clay contained telltale markers of aridity, such as plant material and charcoal. Researchers were able to date the various samples and create a timeline of events.

Megafloods
Munoz described the cycle that doomed the city of Cahokia: "Beginning around 600 AD, high-magnitude floods became less frequent, and indigenous peoples moved into the floodplain and began to farm more intensively and increased their numbers."

Around 1200 AD, +/- 80 years, the North American climate became wetter, and the waters rose, flooding the area with severe and frequent deluges. Crops would have suffered, food stores were probably ruined, and the population would have had to relocate or starve. Floodwaters thought to have risen 33 feet above base elevation, would have jarred a population unprepared for such environmental challenges. After hundreds of years without large floods, it would have had a particularly destabilizing effect.

Archaeologist George Milner at Pennsylvania State University found the analysis convincing but suggested that megafloods might have been only one of many catastrophes that eventually led to Cahokia's downfall, including droughts, fires, cold and hot years -- all leading to social instability. The real problem starts when indigenous people experience back-to-back failures.

The findings by Munoz and colleagues may have finally solved the mystery of the abandoned city of Cahokia and potentially given us a glimpse into what the future might hold for the flood-prone Mississippi Valley region.

What Caused the Fire that Destroyed America’s most prosperous Ancient City of Cahokia?

The ancient city of Cahokia, which was built around 800 AD, was once home to 20,000 inhabitants, stretches of farmland, wealthy communities and surrounded by 120 earthen mounds. However, in 1170 AD, it was ravaged by a massive blaze which left the city in ruins, leading to dramatic changes in their society, culture and architecture. A study has presented strange new evidence leading to exciting theories about the cause of the fire.

The secrets of the ancient city of Cahokia lie buried below where St. Louis, Missouri stands today in an area which is considered the largest and most complex archaeological site north of the great Pre-Columbian cities in Mexico. Cahokia covered a vast area of about 6 square miles. 

The 'Cahokia Woodhenge' site was discovered as part of salvage archaeology in the early 1960s interstate highway construction boom. The Cahokia Woodhenge was a series of large timber circles located roughly 2,790 feet to the west of Monks Mound at the Mississippian culture Cahokia archaeological site in Collinsville, Illinois. They are thought to have been constructed between 900 and 1100 AD; with each one being larger and having more posts than its predecessor. One of the circles was reconstructed in the 1980s. The circle has been used to investigate archaeoastronomy at Cahokia. Annual equinox and solstice sunrise observation events were held at the site.

The mounds were believed to have been built as a place of worship and seem to have had religious significance to the dwellers, with tombs below and places of ceremony on top.  Like the Mayans of Mexico, the civilization was also known to make human sacrifices, including dismembering and burying people alive.

However, one of the greatest mysteries surrounding this World Heritage (1982) listed site, is the devastating fire which ripped through the main ceremonial plaza in the center of the city, destroying many of the buildings which were wooden with thatched roofs. Surrounding this peculiar event is the fact that after the fire the city was a changed place: new architectural designs sprung up, along with new defensive walls. In the original city, the rich and powerful lived in large homes whereas following the blaze all the structures became more regulated and smaller. There was also a sudden influx of clay plates featuring sun symbolism. Was this a sign of a new spiritual or political regime in the area? What is clear is that the fire marked a major turning point in Cahokia's civilization and perhaps the beginning of an end; but why?
University of Illinois at Urbana-Champaign archaeologist Timothy R. Pauketat and his colleagues pored over new dig sites in East St. Louis, and examined the evidence for the fire, and what they found was extremely strange.

The 100 or so thatched buildings that had been destroyed were all packed with luxury items such as clay pots, pipes, and animal bones used in ceremonies, items which were not typically found in regular homes. No garbage pits or normal household items could be found. The houses also appeared to have been hastily constructed, indicating that they were more like temporary structures, and they were placed much more closely together than elsewhere in the city. 

Another strange finding was that the homes which were burned were not rebuilt. Previous digs in Cahokia showed that if houses burnt down, the dwellers would rebuild on top however in this instance, the ashes were swept into piles and left untouched.

The researchers believe that all these clues point to the fact that instead of the fire being an accident or being set by an enemy, it was in fact a mass sacrifice. It wasn't uncommon for the mound builders to burn the structures they built at the top of mounds in ceremonial events. But if this fire was sacrificial, it was on a scale that was unprecedented.
One theory is that the fire marked a decline in the city's power, and the sacrifices were part of an on-going effort to restore the city's former status. If this was the case, it was not successful because by 1400AD, Cahokia and its vicinity had been almost entirely abandoned. It lost power and never regained its reputation again.

Monks Mound at Cahokia was built in decades, not 250 years as previously thought.

By studying plant seeds and spores in the soil used to construct Monks Mound, the largest prehistoric earthen structure in North America, archaeologists have determined that it was not built over the course of 250 years, as previously thought, but in decades, a small fraction of that time.
An artist’s depiction of the Monks Mound is found within the interpretive center at Cahokia Mounds State Park in Collinsville, Illinois.
Monks Mound is in the ruins of the ancient city of Cahokia in Illinois. At its height, about 1,000 years ago, Cahokia was home to as many as 20,000 people. The mound was a series of rectangular terraces that reached 10 stories or 100 feet in height, and its footprint covered 14 acres or 610,000 square feet. The structure had a large public building at its apex, perhaps a temple. There are many other mounds at the site, but Monks Mound towers over them. It was named after Trappist Monks who lived for a very short time on a nearby mound.

Researchers say their new study of the soil in the mound, which began collapsing in 2005, shows that the presence of annual plant seeds and spores, as opposed to perennials, shows the mound was probably built within a few decades. The workers got the soil and sediments from a nearby borrow pit (an area where material like soil, gravel or sand has been dug up for use at another location). Archaeologists surmise that workers got soil from a nearby borrow pit and used it to build the mound. They did so without wheels or beasts of burden, carrying the soil by hand.

The team, led by Dr. Neal Lopinot of Missouri State University, took advantage of the collapse in 2005 and took samples from 22 exposed areas of the mound to study sediments from the floodplain used in constructing it. Apart from remains of perennial plants used for food, they found seeds and spores from wild annual plants that grow once and then die. They concluded from this that the borrow pits where the soil was taken were disturbed frequently.

That leads them to conclude that Monks Mound was built much quicker than surveys in the 1960s seemed to show. Researchers had theorized in the 1960s, based on nine cores taken, that the mound was built in 14 stages over 250 years. The theory seemed credible given Monks Mound’s size and that it was built by hand. Another thing the researchers found was that the seeds were not burned or carbonized, which makes them believe the seeds were covered quickly and not exposed to campfires or cookfires. Plus, they found that soil was cut in sod-like blocks and laid upside-side down in the mound. So some of the mound was built with sod instead of baskets full of soil.

In 2005 experts did emergency, high-tech repairs to the mound to shore it up. The completed repairs have saved Monks Mound from further collapse. It took intelligence to build it to last over 1,000 years without modern technology.

Ceremonial Road Discovered in the Ancient City of Cahokia.

A new study published in the Midcontinental Journal of Archaeology revealed a major ceremonial road running through the heart of Cahokia. Such a road has been the subject of debate and conjecture since the 1920s, and confirming its existence changes our understanding of the prehistoric city. 
A reconstruction of Cahokia with Monk's Mound in the distance.
The ancient indigenous people city of Cahokia near Collinsville, Illinois, is known to have been one of the most sophisticated pre-Columbian settlements north of Mexico. At its peak, it was home to 20,000 people and sprawled over 4,000 acres.

Cahokia was once composed of a collection of agricultural communities across the Midwest and Southeast starting around 800 AD and flourishing between the 11th and 12th centuries. It is a striking example of a complex chiefdom society, with many satellite mound centers and numerous outlying hamlets and villages. It was also a place where the indigenous people made pilgrimages for special spiritual rituals linked to the origin of the cosmos. At its peak, Cahokia boasted some 120 mounds, the largest of which is a ten-story earthen colossus known as Monks Mound. The giant mound is the largest prehistoric earthwork in the Americas, covering over 12 acres and is 100 feet high. An estimated 78,500 square feet of earth was used to build the mound between 800 and 1,350 AD, but not long after this time, Cahokia was mysteriously abandoned. 

The newly discovered ancient road, dubbed the "Rattlesnake Causeway," is an elevated embankment about 60 feet wide that stretches from Cahokia's Grand Plaza south through the center of the city, where it dead-ends in the middle of the burial feature known as Rattlesnake Mound.
Monks Mound with reconstructed stairs in a 2007 photo; repairs done to the mound at Cahokia, in Collinsville, Illinois, in 2005 shored up the mound and kept it from further collapse.
Dr. Sarah Baires of the University of Illinois has suggested that the causeway may have been a literal and symbolic centerpiece of the city, as it is aligned 5° east of north, forming a central "axis" around which the community seems to have been built. Previous research had indicated that the city's major mounds, plazas, and households were oriented along this 5° alignment. Now it appears the causeway marked the axis itself.

Previous research has suggested that Cahokia's buildings align with a celestial event known as the "major lunar standstill," when the moon rises at its southernmost point in the sky. The event occurs once every 18.6 years, and, as seen from Cahokia's Grand Plaza, it is visible over the bluffs south of Rattlesnake Mound, where the causeway ends.

Dr. Baires has suggested that the road's relationship to some of the city's most important mortuary mounds is a key to understanding its purpose. For example, Rattlesnake Mound is a major burial mound with at least 140 individuals buried there, and midway down the road's length is Mound 72, the site of hundreds of burials, including mass graves of sacrificial victims. Baires said that these spatial relationships suggest that the Rattlesnake Causeway served as a conduit between the realms of the living and the dead.

How Waterways, Glacial Melt, and Earthquakes Realigned Ancient Rivers and Changed Illinois Borders.

From about 1673 until 1783, Illinois was known as the Illinois Country (Fig. 1) and the Illinois Territory from 1809 until statehood in 1818. 
(Fig. 1) Original proposed Illinois borders within the Illinois territory. A future addition to Illinois from the future state of Wisconsin.
In the 17th century, the French-built trading forts in the Illinois Country. Louis Jolliet and Father Pierre Marquette suggested a canal from the Illinois River to Lake Michigan to eliminate the portage at Mud Lake. But the canal was never built by the French. At the end of the French and Indian War in 1763, the area was ceded to the British and was then awarded to the new United States by the Treaty of Paris (1783). When the borders of Kentucky and Indiana were established, they formed Illinois' southern and eastern borders (the Ohio and Wabash Rivers and to 42°35" north latitude line, which extended between the Wabash River and the southernmost tip of Lake Michigan). The proposed northern boundary in an 1817 plan considered by the US Congress (derived from the Northwest Ordinance) was a straight line from the southernmost tip of Lake Michigan (in Indiana) to the Mississippi River just south of the Rock River confluence with the Mississippi River.

Nathaniel Pope, Illinois Territory Delegate in the United States Congress, proposed modifying the northern border by moving it 51 miles north for economic reasons and giving Illinois access to Lake Michigan, the Great Lakes, and the St. Lawrence Seaway. Another reason for the northern border move was unstated but was related to slavery. After the Missouri Comprise of 1820, Illinois would become a northern state and a vital part of the Union by 1860. While many in southern Illinois were sympathetic to the Confederate cause during the Civil War (1861-1865), most of the state of Illinois was not.

Many inhabitants living in the northern Illinois Territory (later Wisconsin) objected to the movement of the north boundary, the loss of the Lake Michigan waterfront and the location of a shipping port. The land, water, and population loss delayed Wisconsin's development for 30 years, and Wisconsin finally became a state in 1849. With the help of his brother Senator John Pope of Kentucky, Nathaniel Pope got Congress to move the northern boundary to its present-day location (Fig. 2).
(Fig. 2) Ancient Mississippi River location east of Quad Cites between the Rock and Green rivers to Illinois River and south to St. Louis. Location of the land additions to Illinois from the future states of Iowa and Missouri.
Adding 5,440,000 acres also raised the population to (nearly) 40,000, which was required for statehood. Illinois became a state in 1818. The port area on Lake Michigan became the future town of Chicago (Chicagou) in 1833 (Chicago incorporated as a city in 1837). It linked the two shipping routes with a portage between a small river that drained into Lake Michigan with the Illinois River. In 1848, the Illinois and Michigan Canal was completed, allowing the shipment of goods between the two waterway systems. With tensions rising and Civil War a possibility, the canal provided the Union with a northern route to ship goods without using the Ohio River. After the railroad and canal connected Lake Michigan to the rest of the state, Chicago grew incredibly fast. Chicago is the largest city in Illinois, and the greater Chicago area includes three-quarters of the state's population. The ceding of 8,500 miles of territory and the lakefront property on Lake Michigan by the US Congress to Illinois due to Nathaniel Pope's efforts altered the fortunes of Wisconsin and Illinois. Due to the northern boundary shift, the 5,440,000 acres added to Illinois include very productive soils.

During the Pleistocene Era (2.6 million years ago until about 11,700 years ago), numerous glacial advances covered most of Missouri and Illinois, with the two most recent designated as the Illinoian and Wisconsinan glaciations. Melt waters from these glaciers contributed to the re-alignment of the Mississippi River. The western boundary of Illinois was the Mississippi River (Fig. 2). However, before the Pleistocene glacial period, the ancient Mississippi River passed much farther to the east, as shown by the blue dashed lines. Today's lower Illinois River follows its course. The Wisconsin glacier eventually blocked the ancient Mississippi River, and its terminal moraine (point of furthest advance southward of a glacier) was about 12,000 to 15,000 years ago. The ancient Mississippi River then re-aligned itself to its current position, later used as the western border when Illinois became a state. If the Mississippi River had not been re-aligned, the 7.5 million acres (Fig. 2) would belong to the conditions of Missouri and Iowa. Before 1803, the French controlled the land west of the current Mississippi River and was part of the Louisiana Purchase that year. After Iowa and Missouri became states, they had a border dispute settled by the US Supreme Court. The border between these two states was primarily the 40°35" latitude line, which, if extended into the current area of Illinois between the Illinois and Mississippi rivers (Fig. 2), would determine the acreage each state would have gained if the ancient Mississippi River had not re-aligned. A total of 3.5 million acres would have gone to Missouri and 4 million acres to Iowa. This area includes some of Illinois's most productive soils for corn and soybean production.

Further to the south, the Mississippi River (just south of current Cape Girardeau, Missouri) was re-routed (Fig. 3) at the end of the Great Ice Age. After the last glacial advance, the melting ice flooded and altered the course of many channels and streams, including the Mississippi and Ohio rivers. Approximately 12 to 15 thousand years ago, scientists believe that the Ohio and Mississippi rivers changed course (Fig. 3) south of Cape Girardeau, Missouri.
(Fig. 3) The re-alignment of the Mississippi River south of Cape Girardeau, Missouri. The bedrock lined the Mississippi River channel near Thebes, Illinois.
The 6-mile stretch of the Mississippi River near Thebes, Illinois, is unique. It is the only Mississippi River section in a narrow bedrock-lined valley with rock underlying the navigation channel. Some geologists believe heavy seismic activity along the Commerce Geophysical lineament (a northeast-trending magnetic and gravity feature that extends from central Arkansas to southern Illinois) about 12,000 years to 15,000 years ago created a fault that helped the Mississippi River cut through the "Thebes gap" [1] and made a new confluence 25 miles north of the current confluence, where the River switched from a braided, meandering river to one that cut through rock. The Mississippi River currently forms the state boundary between Missouri and Illinois. 

At Thebes, the Mississippi River is now located 30 miles to the east (Fig. 3) of where the ancient Mississippi River flowed. Before the 20th century, the Mississippi River migrated rapidly by eroding the outside and depositing on the inside of a river bend. Numerous oxbow lakes [2] mark old positions of the channel that have been abandoned. Early Holocene (the term given to the last 11,700 years of the Earth's history) to late Wisconsin liquefaction (conversion of soil into a fluid-like mass during an earthquake or other seismic events) features in western lowlands were induced by a local source, possibly by the Commerce fault (which is north of New Madrid Fault) as a result of earthquake upheaval along the Commerce Geophysical lineament running from central Indiana to Arkansas.
The New Madrid area has been the center of seismic activity for thousands of years, affecting the Mississippi River and perhaps the Ohio River re-routing. The land has rebounded by as much as 13 feet in 1,000 years after the last glacial period. The previous significant seismic activity resulted from an earthquake in 1450-1470 AD and another earthquake in Cahokia, Illinois, in 1811-1812.

Floodwaters of the ancient Mississippi River did not initially pass through this relatively narrow channel and valley. Instead, they were routed by the bedrock-controlled uplands near Scott City, Missouri, and north of Commerce and Benton, Missouri (Fig. 3) to an opening in the upland ridge 40 miles to the southwest. Then the River turned back to the south and merged with the ancient Ohio River near Morely, Missouri. Once floodwaters of the Mississippi River (from the north) and Ohio River (from the east) could cut a valley trench along a fault and through the bedrock-controlled upland west of Thebes. As a result of the Commerce fault, the distance the Mississippi had to travel was shortened from 50 miles to 6 miles. The two historic rivers also once joined at Malden, Missouri; however, the location of the confluence continued to change over time and is now located south of Cairo, Illinois, at Fort Defiance State Park [3]. The confluence of these two mighty rivers created a very rapidly changing channel. It appears that the bedrock-controlled upland was worn away by both rivers after seismic activity. The creation of the Commerce fault contributed to the opening of the bedrock-controlled channel (Fig. 3) after the last glacial advance, approximately 12,000 years to 15,000 years ago.

The modern-day Cache River Valley of southern Illinois (Fig. 4) has a string of tupelo-cypress (trees) swamps, sloughs, and shallow lakes, remnants of the ancient Ohio River whose confluence with the Mississippi River was once northwest of Cairo, Illinois. 
Cache River Valley on the Ohio River in Illinois.
The ancient Ohio River Valley, 50 miles long and 1½ to 3 miles wide, was formed by the meltwaters of northern glaciers as they advanced and retreated in numerous iterations over the last million years. The Mississippi River flowing southward from Minnesota was (and is today) a meandering river of oxbows and cut-offs, continuously eroding banks, re-depositing soil, and changing paths. Its historic meandering is particularly apparent in western Alexander County, Illinois, where topographical maps show oxbow swirls and curves, and Horseshoe Lake, where the ancient Mississippi River once flowed (Fig. 4).
(Fig. 4) The location of the ancient Cache River valley and ancient Ohio and Tennessee Rivers.
The upland hills of the Shawnee National Forest just north and west of the town of Olive Branch and north of Route 3 give way to a low-lying plain between the Mississippi and Ohio rivers. Historically this region has been a delta, confluence, and bottomlands dating back 30,000 to 800,000 years BP (Before Present: where "present" is defined as 1950 AD), with many of Illinois lands shown on the maps located on both sides of the Mississippi River as its channel changed positions over time. As a result, the fertile farmland soils of western Alexander County formed in alluvial (clay, silt, sand, gravel) and lacustrine (sedimentary rock formations which formed at the bottom of ancient lakes) deposits.

Hydrologically, the Ohio River is the main eastern tributary of the Mississippi River. Today it runs along the borders of six states 981 miles west from Pittsburgh, Pennsylvania, to the Mississippi River confluence at Cairo, Illinois and drains lands west of the continental divide from the Appalachian Mountains encompassing all or part of 14 states. The Ohio River, a southwestern flowing river, was formed between 2½ and 3 million years ago when glacial ice-dammed portions of north-flowing rivers.

About 625,000 years ago, the ancient Ohio River, fed by Kentucky's Green and Cumberland rivers, flowed through the Cache River Basin and was smaller than the current Ohio River. The Wabash River (Indiana) had yet to form at that time. The Tennessee River was not a tributary of the Ohio River but formed the main channel before the later Ohio River appeared.

During the Woodfordian period (75,000 to 11,000 years ago), the floodwaters from the historic Ohio River watershed drained into eastern Illinois via Bay Creek (Fig. 4) to the northwest and then west through the Cache River Valley through present-day Alexander County, Illinois, where it converged with the Mississippi River near Morely, Missouri, located west of the Horseshoe State Conservation area. The middle Cache River Valley is 1.3 miles wide due to the previous River having been much larger since it carried waters from the ancient Ohio River Valley and the local waters from the upper Cache River Valley to the Mississippi River.

Extensive deposits of gravel and sand, some as deep as 160 feet, rest on the bedrock floor of the middle and eastern portions of the valley and offer evidence of glacial flooding which carved the valley deeply into the bedrock and then, as the water receded, back-filled the valley with sediments. With increasing sediment fill and climate changes, the ancient Ohio River shifted away from the Cache River Valley and into its present course. This event probably took place between 8,000 and 25,000 years ago. As a result, the Cache River became a slow-moving stream with extensive isolated, low swampy areas with a water table that ebbed and flowed with seasonal precipitation.

The upper and middle sections of the Cache River Valley, the Main Ditch, and Bay Creek are located in the ancient Ohio River Valley, where river water crossed through the state of Illinois approximately 10-20 miles north of the present Ohio River position. The Cache River Valley is deeper at a lower elevation (between 320 and 340 feet) than expected in a slow-moving swampy river system. The New Madrid Fault runs under and near Karnak and Ullin, Illinois, and the Cache River Valley elevation does not fit with the rest of the area. Steve Gough, a land-use change-over-time expert, has suggested a large section under the Cache River Valley sank during a significant earthquake in about 900 AD. The cypress trees in the Cache River Valley swamps are up to 1,000 years old, which would be consistent with this time estimate.
(Fig. 5) The additions and subtractions to Illinois. The orange area is the net border of Illinois without all the Mississippi and Ohio rivers re-routing and the decision to provide Illinois with Lake Frontage on Lake Michigan and connecting waterways.
If all these waterway-related changes had not occurred, the state of Illinois would only have 22 million acres, much smaller than the current 35 million acres (Fig. 5). All but one of the changes would have made Illinois 40% smaller and reduced the current population by more than 80%, since Chicago and Rockford would be in Wisconsin, Cairo, and Metropolis in Kentucky, Quincy in Missouri, and Rock Island, Moline and Peoria in Iowa. Borders such as the Mississippi and Ohio rivers, which were naturally re-aligned, dramatically changed the size and shape of Illinois. Clearly, the location of these waterways matters.

Zephyr Café & Ice Cream Parlor, Chicago, Illinois.

Byron Kouris was among the many Greek-Americans who entered the restaurant business. In the 1960’s he started a chain called the Lunch Pail. He started Byron’s Hot Dogs with locations in Ravenswood (1701 W Lawrence Avenue), Wrigleyville (1017 W Irving Park Road), the Near West Side (680 N Halsted Street) and Lincoln Park (850 W North Avenue).
Zephyr Cafe & Ice Cream Parlor, Chicago, Illinois. (1985)
In 1976 he started Zephyr, a Restaurant & Ice Cream Parlor at 1777 W Wilson Avenue on the Southeast corner of Wilson and Ravenswood Avenues, in an area considered off the beaten path, in the old Pickard Building. Customers somehow found Zephyr and came in droves. So much so that often lines formed down the block on spring, summer, and fall evenings.
The old-fashioned diner had an art deco theme with colored mirrors on the walls with neon lights. They served generous portions of food which were named after entertainment stars of the 1920s and ’30s; such as the Greta Garbo Salad and the Duke Ellington Club.
Zephyr was most famous for its fantastic ice cream creations. There was the War of the Worlds, a gargantuan 10-scoop sundae; the Marathon, a 64-ounce shake. 
Zephyr Café & Ice Cream Parlor's "Son of Frankenstein" is a 6-scoop banana split.
The Frankenstein’s Monster was a large-sized banana split, and the Son of Frankenstein was an even bigger 6-scoop banana split. 
After 30 years in business, Zephyr closed permanently in 2006 because of a lease dispute with the landlord.
The Zephyr location is now O'Shaughnessy's Public House.
