The separate, homeward routes taken by Lewis & Clark on their way east in 1806 are both well worth exploring. A side trip northwest from Great Falls, Montana, traces Lewis' trek through Blackfeet Country to Camp Disappointment and the Two Medicine Fight Site, an area within easy reach of Glacier National Park and Waterton Lakes National Park as they share a border with the Blackfeet Reservation.

While following Meriwether Lewis's route through the Blackfeet Corridor this sign (and others) will appear at times along the highway to depict the route taken by the Corp of Discovery.

The Corps of Discovery II: 200 Years into the Future, the mobile exhibit led by the National Park Service to commemorate the Bicentennial of the original Lewis and Clark 1803-1806 Expedition, will be in Browning, Montana from July 7 - 10, 2006 and hosted by the Blackfeet Nation at the Museum of the Plains Indian. Cultural and historical presentations will be hosted by local Blackfeet members.

A side trip southest to Great Falls, Montana, traces Clarks' journey on the Yellowstone River through Pompey's Pillar Corridor, east of Billings, Montana to the natural landmark that bears Clark's signature carved in stone.
