On May 14, the “Corps of Discovery”—featuring approximately 45 men (although only an approximate 33 men would make the full journey)—left St. Louis for the American interior.READ MORE: Lewis and Clark: A Timeline of the Extraordinary ExpeditionThe expedition traveled up the Missouri River in a 55-foot long keelboat and two smaller boats. In November, Toussaint Charbonneau, a French-Canadian fur trader accompanied by his young Native American wife Sacagawea, joined the expedition as an interpreter. The group wintered in present-day North Dakota before crossing into present-day Montana, where they first saw the Rocky Mountains. On the other side of the Continental Divide, they were met by Sacagawea’s tribe, the Shoshone Indians, who sold them horses for their journey down through the Bitterroot Mountains. After passing through the dangerous rapids of the Clearwater and Snake rivers in canoes, the explorers reached the calm of the Columbia River, which led them to the sea. On November 8, 1805, the expedition arrived at the Pacific Ocean. After pausing there for the winter, the explorers began their long journey back to St. Louis.
