1964 Map of Groundhog Mountain

About this map

Uncompahgre National Forest and San Juan National Forest meet in this high-altitude landscape of the mid-1960s, centered on the massive Black Mesa and Groundhog Mountain. This survey captures a region defined by complex drainage systems and early water management, where numerous headwaters like Beaver Creek and Groundhog Creek descend from the heights. Evidence of local land use is preserved through labels like The Vega and a dedicated Pack Trail that crosses the southern slopes of the mesa. Several high-country reservoirs, including Nelson Reservoir, Joe Redd Reservoir, and Groundhog Point Reservoir, highlight the importance of water storage in this section of the San Miguel and Dolores county line. The topography is anchored by Willow Divide in the southeast, which separates the flow toward the West Dolores River.
