The members of the Corps of Discovery traveled over 3700 miles between May of 1804 and September of 1806. Their journey followed the courses of the Missouri and Columbia rivers. They crossed the Rocky and Bitteroot Mountains. They saw the Pacific Ocean. Although the lands they traveled were largely unknown to Euro-Americans, many American Indian tribes had called these places home for centuries.



These are some of the significant sites of the Expedition:
Fort Clatsop
Spirit Mound
