About this map

Vallecito Reservoir dominates this high-altitude landscape within the San Juan National Forest, shown here during the mid-1960s. The map illustrates the sophisticated infrastructure of the day, from the spillway to the network of campgrounds like Middle Mountain Campground and Pine Point Campground that ring the water's edge. Beyond the recreational shoreline, the terrain rises sharply toward West Mountain and Middle Mountain, where old routes like the Endlich Mesa Pack Trail wind through narrow canyons and basins.

Evidence of local land use is visible in the presence of established outposts like Wits End Ranch and the Vallecito Guard Station. Water management is a primary theme, with a complex drainage system including Grimes Creek, Bear Creek, and the Los Pinos River feeding the basin. Small landmarks like the Gaging Sta and a lone Gravel Pit provide specific touchpoints for researchers tracing the development of this mountain corridor.
