National Parks Passport Program
The National Parks Passport program is a great way to explore the 395 units of the National Park Service. Purchase your passport book at the Mississippi River Visitor Center--or most national park visitor centers--and then obtain stamps for each park you visit. Passport books may also be obtained online at the Eastern National store. Stamps are available at most visitor centers, or ask a ranger where you can have your passport book stamped. Almost all parks have at least one stamp.

At Lake Onalaska, near LaCrosse WI, the Mississippi River is about 4 miles wide. The combination of water held behind Lock and Dam #7 and water held by damming the Black River form this broad reach of the Mississippi River.
