1922 Map of Paradox Valley

About this map

The Dolores River carves a winding path through this western Colorado landscape, which is defined by the unique geology of Sinbad Valley and the Long Park area. Early 20th-century mining activity is evident throughout the terrain, marked by specialized infrastructure like the Pittsburgh Mill, the Joe Junior Mill, and the Rajah Mine. The map shows a region in transition, where isolated mining camps such as Hieroglyphic Camp and Thunderbolt Camp supported the extraction of radium and uranium long before the mid-century boom.
