2011 Map of Devil Mountain

About this map

Tres Piedras Ranch sits at the base of the high country in Archuleta County, where the southern San Juan National Forest landscape transitions from river basins into steep mountain peaks. The Piedra River and its primary tributaries, including the First Fork Piedra River, carve deep canyons through the terrain, most notably at the First Box Canyon and Second Box Canyon. This 2011 survey documents a network of Forest Service roads, such as Sfrd 621 and FS 630.1, which provide access to a rugged interior used heavily for hunting and recreation. Several seasonal basecamps are established here, including the Mesa Spring Hunter Campground near Devil Mountain and the First Fork Hunter Campground to the north. Numerous water sources like Horse Mountain Springs and Farrow Spring are vital markers for both wildlife and backcountry travelers in this vertical landscape.
