On August 12, 1805, an advance party of the Lewis and Clark Expedition crossed Lemhi  Pass into present-day Idaho, the homeland of Sacajawea Sacagawea.

With vital assistance from Sacajawea's people, the Lemhi Shoshoni, the Corps of Discovery crossed over Lost Trail Pass back into today's Montana, only to face the formidable Bitterroot Mountains of north central Idaho. Rescued from starvation and befriended by the Nez Perce Indians, they recuperated, entrusted their horses to the Nez Perce and continued on their epic journey, in cottonwood canoes, to the Pacific Ocean.
