Naperville in Will County, Illinois — The American Midwest (Great Lakes)
Are You Curious About the River?
You might find the answers to your questions here.
How did this river begin?
About 12,000 years ago, the last glacier left behind valleys and ridges (moraines) carved by meltwater. Two of the deeper valleys between moraines became the East and West Branches of the DuPage River (which join about a mile south of here).
Where does the Dupage River end?
The DuPage River flows into the Des Plaines River at Channahon. Along with the Kankakee River, the Des Plaines River merges into the Illinois River, which makes its way to the Mighty Mississippi. The Mississippi River flows into the Gulf of Mexico. Believe it or not, the waters of the Du Page River are headed to the sea.
"To the lost man, to the pioneer penetrating a new country, to the naturalist who wishes to see the wild land at its wildest, the advice is always the same: follow a river. The river is the original forest highway. It is nature's Town Wilderness Road." - Edwin Way Teale
