1985 Map of Anastacio Spring

About this map

Anastacio Spring and other vital water sources like Beef Spring and Barrel Spring define this high-altitude landscape along the border of the Southern Ute Indian Reservation Boundary. Mapping during the mid-1980s reveals a terrain dominated by deeply incised drainages, including Devils Canyon, Albino Canyon, and Simon Canyon. The area is marked by a network of unimproved roads and a distinctive Trail system, suggesting a region primarily utilized for livestock grazing and resource management rather than dense settlement. Notable landmarks such as Devils Washpan and the elevated reach of Pump Mesa stand out among the various pockets and glades. The map also records the jurisdictional transition between La Plata County, Colorado, and San Juan County, New Mexico, capturing a remote corner of the Four Corners region where natural geography dictates the pace of movement.
