About this map

Nikolaus Eureka Mine and the Harlis and Broady Mine anchor this high-altitude landscape in the Inyo County mountains during the 1990s. The terrain is defined by a series of steep ridges and deep valleys, most notably Cowhorn Valley and the eponymous Joshua Flats. The map reveals a history of active resource extraction, indicated by numerous scattered Prospects, a Quarry, and a Borrow Pit.

Mapping by the U.S. Forest Service shows a complex network of 4WD trails and dirt roads navigating the difficult topography, such as the area surrounding Lime Hill. These paths reflect the persistent efforts to access remote mineral claims across the Second Standard Parallel South. For the researcher, the document provides precise locations for specific named mines and survey points that trace the industrial footprint in this corner of the California desert.
