named after Old Cly, a venerated chief who lived in the valley until his death in 1934. When he passed away, they buried him at the foot of Cly Butte. True to Indian custom, they took all his possessions and "knocked them in the head" so that their spirits would go along with the chief. His horse was killed, as were his sheep, goats and cattle, and his saddle and bridle were cut up and left there, so that he could use them for his longest journey
