A crow's nest tree platform atop Latour Baldy one mile south was used beginning in 1930. Then, a 30' pole L-4 tower was constructed atop Frost Peak in 1934. In 1961, construction began on a 30' treated timber R-6 flat, continuing into 1962. In June 1962, a pop-up cupola trailer was moved to the summit and used as the lookout while the tower was being completed. The R-6 tower was gone by 1988.
