2013 Map of Devil Mountain

About this map

The Piedra River and its major tributary, the First Fork Piedra River, carve through this section of the San Juan National Forest in southwestern Colorado. The map documents a landscape defined by dramatic elevation changes, where high summits like Devil Mountain and Mule Mountain look down upon the First Box Canyon and Second Box Canyon. This 2013 survey provides a detailed look at the infrastructure supporting wilderness access, including the Piedra Trail 596 and specialized sites like the First Fork Hunter Campground. Geologic and geothermal activity is evident at the Piedra River Hot Springs, while high-altitude basins like Monument Park and the isolated Tres Piedras Ranch suggest the area's history of grazing and ranching within the national forest boundaries.
