The portage between the Chicago and Des Plaines Rivers served as an important piece of infrastructure for Native peoples long before European settlers arrived in the region. The portage was often called “Mud Lake” because of the way it fluctuated between marsh and dry land over the changing seasons. Called the Portage des Chenes, or “Portage of the Oaks,” by the French, it was one of two portages that connected the Mississippi River watershed to Lake Michigan and the Great Lakes via the Illinois River (the other portage was between the Des Plaines River and the Calumet River). These portages allowed Native people to travel and trade throughout the region for millennia.

Louis Jolliet and Jesuit Father Jacques Marquette, the first European settlers to traverse the Indigenous portage in 1673, were guided every step of the way by Native people. Jolliet and Marquette drew maps based on the expertise provided by Odawa people at the Jesuit Mission of St. Ignace on the upper peninsula of Michigan. They were then led by Myaamia guides as they traveled to the Mississippi River via the difficult Wisconsin and Fox River portage. On their way back, Kaskaskia guides led them through the Chicago portage to Lake Michigan. The entire journey would have been impossible without the extensive knowledge of the Native people who had used the portage for generations.

In spite of this support, the monuments at the site today (one of which is pictured here) show Marquette leading the journey, while the Native guide crouches behind him, in a submissive position. This is one of several depictions of Marquette and Jolliet throughout Chicago, each of which perpetuates a false narrative of the subservience of Native people.
