2012 Map of Signal Hill

About this map

Billie Mountain and the surrounding desert peaks anchor this 2012 survey of a remote corner of San Bernardino County. The landscape is defined by the high ground of the Vontrigger Hills and the namesake Signal Hill, positioned at a convergence of topographic features in the eastern Mojave. Evidence of the region's historical use is visible in the paths of Fort Piute Rd and Lanfair Rd, which cut through the arid terrain. The presence of Tungsten Flat points toward the area's geological and mineral history, identifying a specific basin between the mountain ranges where prospectors and miners once focused their efforts. This modern U.S. Geological Survey sheet provides a precise record of the elevation and drainage patterns across these high-desert landmarks.
