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.
