About this map

The Continental Divide serves as the central spine of this high-altitude landscape, carving a jagged border between Grand and Boulder counties. This terrain is defined by its dramatic glaciated basins, where numerous high-mountain lakes like Spirit Lake and Thunder Lake occupy carved cirques below peaks exceeding 12,000 feet. The hydrological significance of the area is underscored by the complex network of headwaters, including the Middle Saint Vrain Cr, which drain the eastern slopes toward the plains.

Recreational and conservation history is preserved through the overlapping boundaries of Rocky Mountain National Park, Arapaho National Forest, and Roosevelt National Forest. Historic travel routes, such as the Buchanan Pass Trl and East Inlet Trl, navigate the steep grades near Isolation Peak and Mt Craig. These trails provide the only passage through this wilderness, connecting remote landmarks like Fox Park and Pear Reservoir across the alpine divide.
