About this map

The Eldorado Valley Dry Lake (Depression) dominates the northern landscape of this Mojave Desert region, illustrating the stark hydrology of Clark County in the mid-20th century. To the east, the terrain rises into the Eldorado Mountains, a range characterized by steep slopes and isolated summits such as Bump. This survey documents a quiet but active industrial footprint, with several shafts and a shaft located south of the valley floor, indicating small-scale prospecting or mining operations typical of the era. The presence of these mineral extraction points alongside a long-range pipeline suggests a landscape transitioning between traditional hard-rock mining and the infrastructure required for regional energy and resource transport.
