2014 Map of La Tortuga Butte

About this map

The Roskruge Mountains dominate this Pima County landscape, rising sharply from the desert floor to peaks such as Pescadero Mtn and the namesake La Tortuga Butte. This high-desert environment is defined by its drainages and water management, where seasonal flows along the Aguirre Wash and Pescadero Wash intersect with essential livestock or wildlife infrastructure like Indio Tank and White Tank. Located within the Schuk Toak District, the terrain reflects a pattern of isolated water sources and ranching access, most notably along N Agua Dulce Ranch Rd. The passage through the mountains is marked by Aguirre Pass in the southeast, providing a natural corridor through the prominent ridges. This 2014 survey documents the enduring physical character of the Arizona desert, highlighting the vital relationship between the rugged topography and the scarce water resources of the basin.
