Arch Tank Natural Bridge serves as a central geologic landmark in this arid stretch of Yuma County, surrounded by a complex system of drainage washes and water catchment basins. The landscape is defined by its hydrology, where seasonal flows across McPherson Wash and La Cholla Wash dictate the movement through the terrain. These natural water features are supplemented by numerous tanks such as Bandy Tank, Hollow Rock Tank, and Robin Tank, which represent critical infrastructure for survival and transit in the desert environment.
