1989 Map of Copperplate Gulch

About this map

Coronado Mine and the encroaching edge of the Morenci Pit anchor this late 20th-century landscape of extraction along the Graham and Greenlee county line. The map captures a rugged transition where industrial operations meet the natural boundaries of the Apache National Forest and the San Carlos Indian Reservation. Water management is central to this environment, evidenced by the aqueduct, pipeline, and various water tanks serving the mining district. Deep drainages like Eagle Creek and Copperplate Gulch carve through the terrain, while the settlement at Trujillo and an Old Railroad Grade hint at earlier layers of human activity. The presence of Hot Springs and numerous prospects throughout the gulches illustrates the complex geothermal and mineral character of the region during this period of geological survey.
