1953 Map of Placerville

About this map

Placerville sits at the confluence of Leopard Creek and the San Miguel River, serving as a focal point for the ranching and mining activity in this corner of the Uncompahgre National Forest. The landscape is defined by high mesas, including Iron Springs Mesa and Hastings Mesa, which are incised by deep drainage systems like San Miguel Canyon and Leopard Canyon. Evidence of earlier settlement and industry is scattered across the uplands, most notably at the Iron Springs Mesa School (Aband) and the deserted site of Leonard (Aband). Industrial infrastructure is particularly concentrated near the river, where an Aerial Tramway and the Omega Mine indicate the area's mid-century mineral production. This survey, conducted in cooperation with the United States Atomic Energy Commission, reflects the region's importance during the uranium and vanadium mining era, showing how narrow canyons were utilized for transport between isolated mesa-top communities and riverfront processing routes.
