Lewis and Clark Trail


Lewis and Clark's epic 572-mile adventure through Washington and along
the Columbia River was among the most vivid and compelling episodes of
their journey. In 1805, the Corps of Discovery entered present-day
Washington State near Clarkston in the Hells Canyon region where the
Snake, Salmon and Clearwater rivers converge. Beacon Rock is noted as
the first place they detected tidal influences and realized they were nearing
the Pacific.
