Watchman Lookout Station is a two-story rustic stone and wood structure located on an andesite peak on the west side of Crater Lake rim.

The second floor observation deck is 16' 10" by 16' 10' with a full first floor the same size below. A 20' by 14' one-story wing, constructed of massive stone masonry with a flat roof, extends east from the southeast corner of the building. The tower roof is hipped, with green-painted shakes and slender log rafters exposed at the eaves.

Despite alterations, the building's integrity is basically intact, and it is a unique example of rustic architecture as applied to a specialized building type. Merel Sager noted: "After Mr. S. D. Coffman, Fire Control Expert, inspected the building, he stated that he believed it to be the best fire lookout building in the United States."
