1958 Map of Isolation Peak

USGS Topo · Published 1984

About this map

Rocky Mountain National Park and Arapaho National Forest meet along the Continental Divide in this late-1950s survey. The landscape is defined by its dramatic alpine hydrologic system, featuring a dense concentration of glacial lakes and ponds that feed the headwaters of the North St Vrain Creek. From the high elevations of Isolation Peak and Chiefs Head Peak, the terrain drops into deep basins like Ten Lake Park and the basin containing Lake Verna. This map captures the wilderness character of the Front Range before modern high-use trail designations, showing established routes like the East Inlet Trail and the North Inlet Trail. A lone Patrol Cabin near Thunder Lake stands as the only primary structure in this high-altitude interior, while the presence of the Moomaw Glacier and Frigid Lake underscores the extreme climate of these peaks during the mid-20th century.
