The current Ukonom Mountain Lookout is a revision of the CL-100 cabin design on a 14 foot block tower. The structure was completed in 1978 and replaced an earlier L-4 style cab on an enclosed timber tower. The cab from the Lower Devils lookout was transported to this site and installed on a new base.
The earlier lookout was constructed by the Civilian Conservation Corps and was completed in 1934.
While the lookout is located on the Klamath National Forest it is actively staffed and managed by the Six Rivers National Forest.
