Return to St. Louis

  • Vernon Preston


The expedition left its winter quarters at Fort Clatsop on March 23, 1806 and headed up the swollen Columbia River. Clark toured up the Multnomah (Willamette) River, missed during their foggy, rainy descent, reaching a point near modern-day Portland, Oregon. The rapid early spring waters and strong Columbia River Gorge winds created difficulties for the corps. Near Dalles, Oregon, the expedition purchased horses and traveled by land to the confluence of the Columbia and Walla Walla rivers. Instead of returning up the Snake River, they followed an overland Indian trail along the Walla Walla River to the confluence of the Snake and Clearwater rivers.
