Charged with the task of finding a water route across North America, Meriwether Lewis and William Clark set out on their historic 18-month expedition in 1804. Pick up their westward route near the Continental Divide, where in the fall of 1805, their Corps of Discovery traveled along the Snake and Columbia Rivers. On land by private motorcoach and on the river by 221-passenger riverboat, the American Empress, voyage from Montana through Idaho to Washington and Oregon, learning about important expedition sites. Enriching lectures with an onboard historian provide an in-depth perspective of this monumental expedition.
