2011 Map of Turtleback Mountain

About this map

Turtleback Mountain stands as a prominent landmark in this desert landscape of Yuma County, marking a terrain defined by complex drainage systems and the southern reaches of the Gila Bend Mountains. This 2011 survey illustrates the arid hydrology of the region, where seasonal watercourses like Nottbusch Wash, Deadman Wash, and Red Raven Wash carve paths through the alluvial plains. The map records the sparse infrastructure of the era, centered on the corridor of Palomas Harquahala Rd as it traverses the open country. This data is essential for understanding the modern footprint of these desert washes and the topographical relationship between the isolated peaks and the wide drainage basins that characterize this portion of the Arizona desert.
