In September 1805, when the Lewis and Clark Corps of Discovery entered this area, they were hungry and still anxious to find a water route to the Pacific Ocean. Under the direction of the Nez Perce headman Twisted Hair, they were fed and given information about the river ahead, and maps and canoes were made for the river travel to come. On October 7, 1805, the Corps began traveling down the Clearwater River in five newly built dugout canoes, and the next day Twisted Hair and another Nimiipuu guide, Tetoharsky, joined them on the river. Despite dangerous rapids, battered canoes, and water-drenched cargo, the party safely reached the confluence of the Clearwater and Snake rivers near present-day Lewiston, Idaho, on October 10, 1805. Captain Clark recalled landing at the head of a very bad riffle, getting two canoes over well, and freeing a third that struck a rock and was repaired after only a small split in its side, before the party purchased fish and dogs, dined, and continued on. The Clearwater River flows from the alpine North Fork near the Montana border to its confluence with the Snake River in Lewiston, Idaho, through changing landscapes that Lewis described as rocky mountains descending once more to a level and fertile country.
