Roach Lake dominates this arid landscape at the southern edge of Clark County, sitting within the broad Ivanpah Valley. This 2014 survey documents the isolated desert settlements of Roach and Borax, which lie along the transportation corridor that follows the valley floor. To the east, the terrain rises sharply into the high ridges of the Lucy Gray Mountains and Sheep Mtn, creating a dramatic topographical contrast with the flat dry lake bed. The map details the primitive crossings and natural gaps through these ranges, including McCullough Pass and the uniquely named Beer Bottle Pass. This portion of the Mojave Desert remains largely defined by its natural topography and early rail-adjacent outposts, providing a clear record of the region's sparse infrastructure and physical geography.
