About this map

The Continental Divide forms the backbone of this high-altitude landscape along the border of Grand and Boulder counties. Within the Arapaho National Forest and Roosevelt National Forest, the terrain is defined by dramatic peaks and glacial features. Permanent ice fields like the Isabelle Glacier and Arapaho Glacier feed a network of high-country lakes and creeks, including the large Monarch Lake in the northwest.

Evidence of early exploration and transient settlement is found in the presence of the High Lonesome Mine and a web of historic routes such as the Buchanan Pass and Caribou Trail. While most of the map is dominated by named summits like Mount Achonee and Lone Eagle Peak, small human footprints appear at the Shelter Rock Campground and Crater Lake Campground. This survey captures the alpine wilderness before later shifts in forest management, documenting the precise locations of remote passes like Pawnee Pass and Caribou Pass.
