1989 Map of Silver Bell East

About this map

Silver Bell (Site) sits at the base of the Silver Bell Mountains, where the landscape reveals a clear transition from natural desert peaks to an active industrial landscape. The map shows the extensive footprint of resource extraction in this corner of Pima County, with the Oxide Pit and various Prospect markings, Adit locations, and Mine Shafts scattered across the southern terrain. Below Portland Ridge, the presence of Tailings and Sewage Disposal Ponds indicates the infrastructure required to support the mining operations that defined this area’s economic character during the late twentieth century.
