About this map

Spring Mountains peaks and the dry basins of the Mojave Desert dominate this mid-century survey of the Nevada-California border. The Union Pacific railroad tracks provide the primary corridor for human activity, connecting small sidings and outposts like Roach, Borax, and Calada across the arid landscape. The geography is defined by the massive dry beds of Roach Lake and Ivanpah Lake, which serve as stark markers between the mountain ranges.

Prospectors and miners left a significant mark on the terrain, particularly around the high elevations of Devil Peak. Remote operations such as the Christmas Mine, New Year Mine, and Addison Mine are documented in the northern reaches, while the Lucy Grey Mine and Umberger Mine suggest the widespread search for mineral wealth. The Von Schmidt Line cuts diagonally across the quadrangle, representing an earlier attempt to survey the state boundary between Clark and San Bernardino counties.
