2021 Map of South of Sentinel

About this map

Tenmile Wash carves through this arid stretch of the Sonoran Desert, defining the drainage patterns of the southwestern Maricopa County landscape. In the southern portion of the sheet, the volcanic topography of the Crater Range rises sharply from the desert floor, with intricate contouring illustrating the complex ridges and basins of this geological formation. The map documents the vast, open character of this region as it appeared in 2021, showing a terrain largely defined by these natural features rather than human settlement. The intersection of the desert wash and the rocky outcrops of the range creates a distinct environment for understanding the hydrology and geomorphology of the area south of the Gila River corridor.
