About this map

Powderhorn and the small settlement of Spencer anchor this high-elevation mining landscape in Colorado. The map reveals an area defined by mineral exploration and thermal features, notably the Cebolla Hot Springs and the Cebolla Creek Titaneferous Iron Deposit. Resource extraction is a dominant theme, with numerous named operations ranging from the Old Lot Mine and Seventy-six Shaft Mine to more modern industrial sites like the Rare Earth Mining Company Mine and the Iron Hill Columbium Deposit.

The rugged terrain is drained by Cebolla Creek and Willow Creek, with agricultural holdings like Youmans Ranch and Howard Ranch occupying the more level reaches. Geologic interest is concentrated around Iron Hill and the Iron Hills Manganese District Mine, while the infrastructure of the Powderhorn Post Office and the Soderquist Dam at Soderquist Reservoir support the local community. This survey provides a look at a specialized landscape where ranching, mining, and unique geological deposits intersect.
