2021 Map of South of Gila Bend

About this map

Quilotosa Wash and Sauceda Wash carve intricate patterns through this desert landscape south of Gila Bend. These ephemeral drainage systems are the defining physical features of the region, dictating the natural flow of water across the arid basins of the Sonoran Desert. The map serves as a detailed study of the land's hydrology, where the Sand Tank Wash also emerges in the northeastern corner, illustrating the complex network of dry streambeds that characterizes this corner of Maricopa County. The precise surveying by the U.S. Geological Survey reveals how the topography is shaped by these watercourses, providing essential data for understanding the environmental and geographic layout of the territory during the early 21st century.
