The National Park Service's unique contribution to the bicentennial—the Corps of Discovery II: 200 Years to the Future —is a traveling education center that will recreate the epic journey and be the unifying component for the Lewis and Clark Bicentennial observance.

BLM has a waterproof floater’s map for the wild and scenic section of the Missouri River. It comes in two parts and provides information about making the trip as well as a mile-by-mile report. The maps are $4 for each part and are available at most BLM offices (maps 1 & 2 are printed back-to-back and cover Fort Benton to Slaughter River; maps 3 & 4 cover Slaughter River to James Kipp campground).
BLM has also recently published a map in two parts for the Yellowstone River from Livingston to the mouth of the Bighorn River near Custer.
