Chicago's Guarie River.

Guarie (or Guare) River was the original French name of the north branch of the Chicago River.

The first non-indigenous settler at Wolf Point may have been a French trader named Guarie, who considered the north branch of the Chicago River as a separate stream from the south fork.

Writing in 1880, Gurdon Hubbard, who first arrived in Chicago on October 1, 1818, stated that he had been told of Guarie by Antoine De Champs and Antoine Beson, who had been traversing the Chicago Portage annually since about 1778. Hubbard wrote that De Champs had shown him evidence of a trading house and the remains of a cornfield supposed to have belonged to Guarie. The cornfield was located on the west bank of the North Branch of the [Chicago] River, a short distance from the forks at what is now Fulton Street. 
Early settlers called the North Branch of the Chicago River the Guarie River.
