Lewis And Clark National Historic Trail

Lewis And Clark National Historic Trail

The Lewis and Clark Expedition, which occurred from 1804 to 1806, was one of the most dramatic and significant episodes in the history of the United States. It stands, incomparably, as an epic journey in the exploration of the American West. The Idaho portion of the trail, which is on a tree-lined ridge high above the Lochsa River, represents the most difficult part of the Corps of Discovery's trek across the western territory to discover a passage to the Pacific Ocean.
