1991 Map of Cordero Mine

USGS Topo · Published 1991

About this map

The Cordero Mine and Mc Dermitt Mine dominate this high-desert landscape on the border of Humboldt County, Nevada, and Malheur County, Oregon. In the early 1990s, the area's industrial character is defined by extensive mercury mining operations, marked by numerous prospect pits, mine dumps, and large tailing ponds north of McConnell Canyon. The map reveals the intricate network of mining infrastructure, including a substation and a major transmission line crossing the valley floor. Away from the industrial activity, the Quinn River Valley and McDermitt Creek provide water for cattle operations like the Washburn Ranch and Lucky Seven Ranch. The eastern edge of the sheet includes the boundary of the Fort Mc Dermitt Indian Reservation, highlighting the intersection of tribal lands, private ranching, and large-scale resource extraction in this corner of the Great Basin.
