Appointed by President Thomas Jefferson, Captains Meriwether Lewis and William Clark were charged with finding the Northwest Passage to the Pacific Coast. The Lewis-Clark Expedition was one of the most significant exploration events in the history of the United States. The explorers camped overnight on an island near the confluence of the Snake and Clearwater rivers located near what is now the sister cities of Lewiston, Idaho and Clarkston, Washington.

Some of the Lewis and Clark sites include:

  • Confluence Center Atop the levee in Lewiston, Idaho near the confluence of the Clearwater and Snake rivers. A historical marker for the October 10, 1805 campsite of the expedition is located here. Nearby are several open-air interpretive displays, including a dugout canoe. Nez Perce lore is conveyed in  Nancy Dreher’s Tsceminicum sculpture. Parking is off the west end of D Street in Lewiston.
  • Lewis and Clark Timeline Hells Canyon Resort Marina in Clarkston. View beautiful sidewalk etchings depicting the adventures of the expedition.
