Pahrump Valley and Mesquite Valley converge on this map along the desert border of Nevada and California. The landscape is defined by long-established transit corridors and historic survey lines, most notably the Von Schmidt Boundary (1873) which cuts diagonally across the terrain. This line, established by Allexey W. Von Schmidt in the late 19th century, remains a critical marker for researchers tracing the evolution of state borders in the American West.
