The Swisshelm Mountains dominate this high-desert landscape in Cochise County, defined by a legacy of heavy prospecting and mineral extraction. This study reveals a topography dense with mining infrastructure, ranging from an Open Pit Mine and various Mine Shafts to numerous Adits and Prospects scattered across the elevations. The presence of Usmm 12 suggests a formal mineral monument used for early surveying of these mining claims.
