About this map

The Dolores River winds through the western edge of this San Miguel County landscape, defining a region of intense geologic transition and mineral exploration. In the mid-century era, the terrain between Gypsum Valley and Disappointment Valley was a hub of mining activity, with numerous sites such as the Chile No 5 Mine, Mexico Mines, and the Maggie No 2 Mine scattered across the ridges. The extraction economy is further evidenced by a prominent Pipeline and several Oil Wells located near Hamm Canyon.
