1961 Map of Chalk Mountain

About this map

Chalk Mountain and Crater Peak anchor a high-altitude landscape defined by its complex irrigation and water storage infrastructure along the border of the Grand Mesa National Forest and Gunnison National Forest. This 1961 field-checked survey reveals an extensive network of small upland reservoirs, including the uniquely named Holy Terror Res, Dogfish Reservoir, and Goodenough Reservoir, which managed the snowmelt for downstream use. The terrain is marked by geological features like the Lombard Slides and the prominent Overland Ditch, illustrating how early 20th-century water engineering adapted to the challenging topography of the Mesa and Delta county line. Backcountry access is documented through established routes such as the Leroux Trail and Doughty Park Trail, which connect these remote water bodies and mountain peaks.
