About this map

Pahrump Valley straddles the high-desert border between California and Nevada in this mid-1980s provisional study. The settlement of Calvada Springs serves as a primary reference point, situated near the intersection of the modern Old Spanish Trail Highway and the historic Von Schmidt Boundary (1873). This boundary line represents the 19th-century effort to define the state line, which remains a critical marker for local land records and historical surveys.

Industrial activity is noted by several Borrow Pit locations and a Shaft, indicating mining or resource extraction in the arid terrain. The map also delineates the jurisdictional transition between Clark Co, Nevada, and Inyo Co, California. The presence of numerous Well labels underscores the vital importance of water access in this desert basin, illustrating the basic infrastructure required for development in such a specialized environment.
