USGS Topo · Published 1963About this map
Keystone and the high peaks of the Arapaho National Forest define this 1958 survey, conducted as the infrastructure of the Continental Divide was being reshaped. Significant engineering is evident in the Harold D Roberts Tunnel and a Diversion Ditch near the North Fork Snake River, reflecting the Denver Municipal Water Works' influence on the drainage basin.
