The Volcanoes of Lewis and Clark

On October 7, 1805, Lewis and Clark and the "Corps of Discovery" began their journey down the Clearwater River and into the volcanics of the Pacific Northwest. The Corps travelled from the Clearwater to the Snake and down the "Great Columbia." finally reaching the Pacific Ocean on November 15, 1805. Along the journey they encountered the lava flows of the Columbia Plateau, river channels carved by the great "Missoula Floods." and the awesome beauty of five Cascade Range volcanoes.
