 Following an arduous trek through the Bitterroot Mountains, suffering through a mid-September snowstorm and near starvation, the Corps of Discovery expedition camped with the Nez Perce tribe on the Weippe Prairie outside of present-day Weippe in 1805.With the assistance of the Nez Perce, the expedition recuperated and constructed burned-out canoes at Canoe Camp in October 1805 and then paddled down the Clearwater, Snake, and Columbia rivers and met the Pacific Ocean a month later at present-day Astoria, Oregon.Elias D. Pierce and Wilbur F. Bassett made the first discovery of gold in Idaho, on Orofino Creek (Canal Gulch) in 1860, north of present-day Pierce.
