1. Drewyers River Marker

Inscription. The Palouse River was first named Drewyers River by Lewis and Clark in honor of George Drouillard a civilian member of the expedition which arrived in this area on Oct. 13, 1805. Throughout the Lewis and Clark journals "Drewyer", as his name was spelled by Lewis, was praised for his valuable services as tracker, hunter, scout and interpreter. He became a boon companion to Lewis and was considered one of the two or three most valuable men on the expedition. Drouillard's French Canadian and Indian ancestors had rendered similar services to the French in the settlement of French Canada. Two years later Drouillard returned to the west with fur traders and, in 1810 lost his life in a fight with Indians at Three Forks, Montana.

Erected by Washington State Department of Transportation (and co-operating agencies). (Marker Number 34.)
