Developed with a camp 1/4 mile south of the summit in 1909, a log cabin was added in 1918. Then a cupola cabin was built in 1928, followed up by a 40' pole L-4 in 1938. The U.S. Air Force developed the summit as a radar site after World War II. A 41' treated timber R-6 flat tower, constructed in 1964, was abandoned in the 1970s. With no guy cables or lightning hardware, the tower managed to stay upright through the 1980's when it was torn down in 1989. The top 30' of the superstructure was moved to Big Meadow Lake west of Ione, WA, to become a wildlife observation tower.
