1964 Map of Devil Mountain

About this map

San Juan National Forest defines this high-elevation landscape in southern Colorado, where the First Fork Piedra River cuts a deep path between timbered peaks. Surveyed in the mid-1960s, the terrain is defined by a network of historic access routes, including the First Fork Pack Trail and the River Pack Trail. These paths connect remote outposts like Tres Piedras Ranch and established seasonal sites such as Hunter Campground. High points like Devil Mountain, topped by the Devil Mountain Lookout Tower, provided critical vantage points for forest management. The presence of Prospects in the high canyons suggests early mineral exploration, while the numerous water sources like Mesa Spring No 1 and Horse Mountain Springs indicate a landscape heavily utilized for both timber management and seasonal grazing.
