Cadiz Valley dominates this 1980s landscape, where the stark desert floor meets the rising terrain of the Mojave. This provisional survey captures the transition from the arid flats toward the edge of Cadiz Lake, a significant dry lake bed in this portion of San Bernardino County. The map is defined by a rigorous line of geodetic control, following a series of benchmarks including Bm 14 Jgh 259.1 and Bm 15 Jgh 258.9 that trace a precise path across the valley. These markers represent the infrastructure of mid-century desert surveying, providing fixed elevation points in a terrain otherwise characterized by shifting alluvial fans and isolation. The absence of permanent settlements highlights the environmental extremity of the region during this era of field checking.
