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 canyon-carved topography of San Miguel County. The landscape is defined by massive flat-topped features like Iron Springs Mesa and Specie Mesa, which rise sharply above the river valleys. This 1953 survey, produced in conjunction with the United States Atomic Energy Commission, captures the region's transition from early mining to mid-century industrial interests. Evidence of former mountain life is found at the Iron Springs Mesa School (Aband) and the settlement of Leonard (Aband) along Leopard Creek Canyon. Resource extraction is noted at the Omega Mine and an Aerial Tramway, reflecting the difficult logistics of moving ore across the steep terrain of the Uncompahgre National Forest.
