This driving trip begins where Captain Clark intersected the Yellowstone River and heads east on the return route. We follow the Roche Jaune (as the French explorers had named it) toward the eventual confluence with the Missouri where the Corps would be together again and focused on their final leg of the expedition and the return to St. Louis.
On July 3, 1806, after nearly three years of exploration, the Corps of Discovery divided to cover more ground. Clark led his detachment south along the Bitterroot River, crossing Gibbon’s Pass on July 6 before reaching Camp Fortunate on July 8, where they retrieved cached supplies, including long-missed tobacco. By July 13, at the Three Forks of the Missouri, Clark sent Sgt. Ordway downriver to rendezvous with Lewis while he led the rest toward the Yellowstone.

Begin your journey in Livingston, Montana, a historic town nestled along the Yellowstone River, which William Clark followed on his eastward return in 1806. This scenic waterway offers excellent opportunities for fishing, boating, and riverside walks that echo the expedition’s path. Visit the Yellowstone Gateway Museum to explore exhibits on the region’s Indigenous cultures, early explorers, and the lasting impact of the Lewis and Clark Expedition.
Traveling east from Livingston along Interstate 90, follow the Yellowstone River through Big Timber and Columbus, tracing the very landscapes Clark and his men navigated by canoe. These rolling plains and river valleys remain largely unchanged, offering a glimpse into the untamed beauty of the American West as experienced over two centuries ago.
