The Chicago Portage is the birthplace of Chicago. A small portion of the historic
connection between the Great Lakes and the Mississippi waterways is preserved
in the Forest Preserve District of Cook County’s Portage Woods and Ottawa Trail
Woods in Lyons, Illinois. It is one of only two National Historic Sites in Illinois and
one of the few in the country that is not owned by the National Park Service.

Chicago owes its very existence as a city to the location of the Chicago Portage. Long
used by Native Americans, the portage was revealed to French explorers Pere Jacques
Marquette and Louis Jolliet in 1673. It provided an easy connection between the Atlantic
and the Gulf of Mexico by linking Lake Michigan with the Mississippi River. Jolliet
suggested then a that a short canal cut through the portage area would create a
vital transportation and trade connection.

Although it was more than 160 years before it was dug, watered and opened, the 97 mile
long Illinois & Michigan Canal (I&M Canal) was completed in 1848. It connected the
Chicago River at Bridgeport to LaSalle/Peru on the Illinois River and ultimately completed
the connection envisioned by Jolliet. The canal and its construction were the immediate spurs
to Chicago’s exponential growth from a small settlement to a major city and the transportation
hub of the nation.

Since that time nearly every site of Chicago’s origin’s has been destroyed. The remains
of Fort Dearborn are buried under three layers of Wacker Drive, you can't visit
DuSable & Kinzie's cabin, the Portage Trail is completely paved over and old “Mud Lake”
is now the site of the world’s largest sewage treatment plant. The Chicago Portage National
Historic Site is the only major remnant of the discovery and settlement of Chicago.

This is the only place where you can stand on the same ground walked upon by the
explorers, early settlers and creators of Chicago. You can stand on the footbridge over the short
remnant of Portage Creek, stretch out your arms and know that Jolliet, Marquette, LaSalle,
Tonti, Point du Sable, Kinzie, Hubbard, Ogden, and countless anonomous others from the
discovery, exploration and creation of Chicago passed within an arm's length of you. The
late Tribune columnist John Husar, after touring the site called it: “Our sacred ground”.
It is certainly Chicago’s “Plymouth Rock”.
