Started in 1922 with a 20' platform tower, log cabin and barn, a 50' pole tower with 7'x7' cab replaced the first tower in 1930. In 1943, a gable roof L-4 cab was moved from another site for living quarters on the ground, later remodeled for storage, and is still on the summit. The present standard 53' CT-2 treated timber tower with standard 1936-model L-4 cab, built in 1950, was last staffed in 1978. Spyglass is unique in that it still has two generations of lookout structures, the 53' tower with L-4 cab, and the L-4 ground house. At the time of the 1973 consolidation in North Idaho, Spyglass was one of two Magee Ranger District Lookouts.
