I grew up in Palos Heights, about ten miles south of the portage.
The historical marker at the site, which is near Harlem Avenue and 48th Street.
This iron sculpture, designed by The sculpture is by Ferdinand G. Rebechini, depicts Marquette, Jolliet, and a Native American guide at the portage.
Portage Creek, partially frozen over here, is a tributary to the Des Plaines River.
Marquette and Jolliet immediately grasped the importance of their discovery--and they envisioned a canal to connect the Great Lakes Lakes watershed--the Chicago River--and the Mississippi River watershed of which the Des Plaines is a part. In 1848 their vision became reality when the Illinois & Michigan canal opened. In 1900 the I&M was superseded as a transit waterway by the Chicago Sanitary and Ship Canal.
By most accounts much of the portage area looks as it did in 1673.
