1958 Map of Isolation Peak

About this map

Rocky Mountain National Park and the adjacent Arapaho National Forest meet at the Continental Divide in this mid-century survey. The landscape is defined by its high-altitude hydrology, with a dense network of glacial tarns including Lake Verna, Thunder Lake, and Bluebird Lake feeding numerous drainages. A Patrol Cabin situated near the headwaters of the St. Vrain suggests the remote administrative presence required to manage these wilderness boundaries during the 1950s.
