2011 Map of Drew Spring Well

About this map

The Sheridan Mountains dominate the southwestern quadrant of this arid landscape in Pima County, Arizona. This 2011 survey illustrates a sparse but vital desert infrastructure centered on water access and a primary network of tribal roads. Drew Spring Well serves as a critical local landmark in the western flats, where the topography transitions from high peaks to alluvial plains. The map traces the drainage patterns of Anegam Wash in the southeast, alongside a geometric grid of thoroughfares including Indian Rte-15 and Indian Rte-40. These routes intersect across the desert floor, indicating the essential corridors of travel within the Sif Oidak District and the Tohono O'odham Nation. The stark contrast between the prominent mountain ridges and the expansive washes reveals the fundamental geological and hydrological character of this portion of the Sonoran Desert.
