DescriptionThe Lewis and Clark Expedition’s return trip from the Pacific Coast had its share of significant discoveries. Between July 22 and 26, 1806, Capt. Meriwether Lewis and 3 men explored the Marias River to determine the northern boundary of the Louisiana Purchase. They also hoped to find a short portage between the Marias and Saskatchewan rivers that would allow American traders access to some of the western Canadian fur trade. At the northernmost point of this trip, Lewis named a campsite Camp Disappointment because from a high overlook he saw Cut Bank Creek curve southwest toward the Rocky Mountains. He then knew that the boundary of the United States did not extend to 50º north as they had hoped. Camp Disappointment, which has restricted public access, is commemorated with a highway marker and roadside monument on US 2.
