About this map

Oreana sits at the base of the West Humboldt Range, serving as a focal point for the mining and transport activity in this part of Nevada during the 1980s. The landscape is defined by the contrast between the flat valley floor where the Humboldt River flows and the steep, mineral-rich slopes to the east. Evidence of the region's industrial past and then-current operations is visible through an extensive network of prospects and established sites, including the Johnson-Heizer Mine, Rosal Mine, and Adriene Mine.

Transport corridors like the Old Railroad Grade and the Levee track the movement of goods and water through the basin. The eastern portion of the map is particularly dense with mining activity, especially around Limerick Canyon and Rochester Canyon, where Mine Shafts and Mine Dumps are frequently noted. This survey captures a moment when traditional resource extraction continued to shape the geography of Pershing County.
