About this map

Gunnison National Forest dominates this high-altitude landscape in the Colorado Rockies, where the topography is defined by the massive volcanic and sedimentary formations of the Anthracite Range. The map reveals a complex system of drainage and high-country passes, including the notable Beckwith Pass and Swampy Pass, which historically served as vital corridors through the mountainous terrain. The northern reaches are characterized by the distinct geological features of East Beckwith Mtn and the striking linear formation known as The Dyke.

Glacial and alpine water systems are prevalent, from the headwaters of Ruby-Anthracite Cr to high-elevation bodies like Lost Lake Slough and Costo Lake. In the southern portion, the terrain transitions into the West Elk Mountains near Storm Ridge. The presence of Horse Ranch Park and trails like Lowline suggest a landscape managed for both timber and recreation, while labels like Mill Castle hint at the historical mining or ranching infrastructure that once supported localized industry in these remote basins.
