Copper Mountain Lookout

History:
The lookout was built around 1932. It is a gable-roofed L-4 cab that is used by wilderness rangers in the summer. Although remote, the destination has always been popular. It seems the trailhead is the same today as it was in the 1930s. We learn from an October 1936 issue of Sis Twenty-Six discussing Copper “The most remote station with a ten mile one way hike had about 37 visitors this season.” In 1942, the lookout was used by the Army as an Aircraft Warning Service outpost. The AWS built a sleeping quarters too although no image is available of this structure. It should be noted that AWS records also show a cabin was built at Hannegan Pass with AWS funds. It is unclear if the plan was to use Hannegan Pass during the winter but no records make this case. One document below (before the first winter) says that Copper Mountain Lookout should be discontinued for winter use.
