1956 Map of Lake Agnes

About this map

The Continental Divide serves as the prominent natural boundary on this mid-century survey, separating the headwaters and drainage basins in the high country of Grand and Jackson Counties. The landscape is defined by the intersection of the Routt National Forest and Arapaho National Forest, where high-altitude water management is evident through a network of ditches and reservoirs. Features such as the Basin Reservoir, Milk Creek Reservoir, and an Aqueduct illustrate the vital role of water engineering in this alpine environment.
