1958 Map of Isolation Peak

USGS Topo · Published 1984

About this map

The Continental Divide serves as the central spine of this high-altitude landscape, separating the headwaters of the Arapaho National Forest to the west from the Roosevelt National Forest to the east. Within the boundaries of Rocky Mountain National Park, the terrain is defined by a dense concentration of glacial lakes and cirques, including Thunder Lake, Bluebird Lake, and Lake Verna. This 1958 field-checked survey captures the area’s preservation as a primitive wilderness, dominated by massive granite summits like Isolation Peak and Mt Alice. The network of packing routes, such as the East Inlet Trail and Lion Lake Trail, illustrates the early recreational footprint in the Front Range before modern accessibility changes. The presence of features like the Moomaw Glacier and Indigo Pond highlights the sub-alpine environment that has long drawn mountaineers and researchers to these specific peaks and valleys.
