1961 Map of Chalk Mountain

USGS Topo · Published 1984

About this map

Chalk Mountain stands at the boundary of the Grand Mesa National Forest and Gunnison National Forest, overlooking a complex system of water management. The high-altitude landscape is characterized by a network of small reservoirs and irrigation features, including the Overland Reservoir and the Overland Ditch. These 1961 field observations reveal a topography of named peaks and ridges such as Doughty Mtn and Willow Ridge, while the 1979 revisions highlight additional water structures like Holy Terror Res and Lucky Find Reservoir. The map illustrates the region's reliance on mountain runoff, with numerous colorfully named catchments like Skimmed Milk Res and Dogfish Reservoir positioned along the drainage of Leroux Creek and its various forks. Distinctive terrain features, such as the Lombard Slides and Dyke, provide a clear picture of the geological character of the Mesa and Delta County borderlands.
