Calpine is a forest fire lookout tower that was constructed in 1934 by the Civilian Conservation Corps, and is one of three remaining examples of the enclosed windmill-style lookout in California. The lookout was actively used every summer until 1975. It is a three-story structure with external stairs. The top room or observation cab is the only rented space at this time. Calpine sits at an elevation of 5,980 feet in the Sierra Nevada Mountains of Tahoe National Forest, approximately 40 miles from Truckee, California. The lookout is ideally suited for over-the-snow ski or snowmobile access. The lookout does not have electricity or water. It contains propane-powered appliances.
