Part 3 of the Lewis and Clark Expedition chronicles the journey from Fort Mandan to their arrival at the Pacific Ocean. The most challenging portions of the trek west take place here: the portage around the Great Falls, and crossing the Bitterroot Mountains using the Lolo trail. Without the contributions of Sacagawea and the Nimiipuu woman named Watkuweis, this expedition would have failed! After arriving at the Pacific Ocean, the Expedition spent the winter of 1805-1806 at Fort Clatsop.
