About this map

The Dolores River cuts through the western edge of this 1960 landscape, a region defined by dramatic geological formations and a mid-century mining economy. The map illustrates the distinct separation between Gypsum Valley to the north and Disappointment Valley to the south, connected by the drainage of Big Gypsum Creek and Disappointment Creek.

Prospectors and mining historians will find several named operations scattered across the heights, including the Maggie No 2 Mine, Uncle Sam Mine, and the Carnation Mine. Evidence of modern infrastructure appears in the form of a remote Airstrip near Nicholas Wash and an Oil Well to the east. The terrain is further marked by family or locally named landmarks such as Hamm Canyon, Cape Horn, and Joe Davis Draw, providing a detailed look at San Miguel County before contemporary developments altered the access and visibility of these backcountry sites.
