Ward Valley and the expansive Mojave Desert terrain define this 2015 survey of San Bernardino County. The landscape is characterized by a network of drainage channels, most notably Sunflower Wash, Homer Wash, and Painted Rock Wash, which illustrate the natural water flow patterns across this arid basin. This topographic record emphasizes the importance of ephemeral watercourses in desert geomorphology, showing how they shape the alluvial plains of the valley between the surrounding mountain ranges. The map also delineates the precise boundaries of the Public Land Survey System, including townships such as t5n r19e and t4n r20e, providing essential data for land management and ownership within this federally overseen territory.
