1964 Map of Vallecito Reservoir

About this map

Vallecito Reservoir dominates the drainage basin of the Los Pinos River in this mid-1960s survey of the high country. The map captures a landscape dedicated to recreation and water management within the San Juan National Forest, evidenced by the high density of campsites such as Vallecito Campground and Old Timers Campground. The rugged geography of West Mountain and Middle Mountain is traversed by the Endlich Mesa Trail and various pack routes, providing access to remote high-altitude features like Lake Eileen and the Chain Lakes. Beyond the water's edge, the map documents localized ranching and administration at the Vallecito Guard Station, Wits End Ranch, and Wilderness Trails Ranch. A small Gravel Pit near the northern inlet of the reservoir indicates the material needs for maintaining the area's infrastructure and roads.
