The Castle Mountains, highest point Elk Peak, el. 8589feet,[1] are an island range east of White Sulphur Springs in Meagher County, Montana, United States.[2] About 30,000 acres of the Castles were roadless as of 1995.[3] The western portion of the Castles are moist, while the eastside is dry, porous limestone hills.[3] The range gets its name from "castle turrets", 50-foot high igneous rock spires on the western slopes.[3] The range was the focus of mining activity in the previous century; crumbling remains of old miners' cabins and diggings are present throughout the area. The landscape is characterized by a central cluster of peaks over 8,000 feet and extensive grassy parks surrounded by lodgepole pine and limber pine.[3] The Castles are lightly used by recreationists except for hunters in the fall.[3] On the peak of Castle Mountain itself is a logbook for the few who reach the top. There is no trail that leads to the peak.
