2011 Map of Weminuche Pass

About this map

Weminuche Pass serves as a critical divide in this high-altitude landscape where the headwaters of the Rio Grande meet the drainage of the Los Pinos River. This 2011 survey captures a region defined by water management and wilderness recreation, anchored by the massive Rio Grande Reservoir and its associated Rio Grande Dam. The presence of Fuchs Ditch and multiple reservoir structures, including the Squaw Lake Dam, illustrates the engineering required to harness snowmelt in the San Juan Mountains. Cultural landmarks like Stage Station Flat and Horse Thief Pasture suggest a history of early transit and livestock grazing, while modern access is maintained through Co RD 18 and the Thirtymile Campground. The terrain is marked by steep glacial features such as Snowslide Canyon and Rincon La Vaca.
