About this map

High-elevation water management and topographic divides characterize this 1960s survey of the San Juan and Uncompahgre National Forest lands. The landscape is defined by the massive bulk of Black Mesa and the prominent Groundhog Mountain, which overlooks a series of critical drainage systems. Water resources are central to the map's detail, featuring the Nelson Reservoir, Joe Redd Reservoir, and Groundhog Point Reservoir, alongside the headwaters of numerous creeks like West Beaver Creek and Little Fish Creek.

The presence of a Pack Trail winding through the southern terrain highlights the remote nature of the Willow Divide before it drops toward the West Dolores River. This area, split by the San Miguel Co Dolores Co line, reflects the mid-century infrastructure of the Colorado high country, where isolated settlements like The Vega stood as small outposts in a vast network of forest boundaries and tributary streams.
