The Double Diamond Dude Ranch Dining Hall, constructed in 1945, is significant for its association with rustic architecture. Significant design features include the log construction, massive stone fireplace, ranch-style floorplan, eave brackets, extensive fenestration, and the interior floorplan and finishes.

Frank Williams and Joseph Clark Jr. opened the Double Diamond Dude Ranch in 1924 on a small 14-acre parcel of land. Initial infrastructure included a log kitchen/dining room cabin, a log lounge cabin, a small commissary cabin, and about a dozen tent cabins. The land base was expanded in 1928 when Williams and Clark purchased 40 acres of the adjacent Manges homestead. The ranch provided tent accommodations and a wilderness experience for teenage boys until 1943 when Williams constructed cabins tailored to tourists in search of more comfortable quarters. Much of the historic dude ranch was destroyed by the Taggart Lake Fire that swept across the south edge of the complex in 1985. Only five cabins and the dining hall survived the fire.
