2014 Map of Slumgullion Pass

About this map

Castle Dome Mountains dominate the western half of this 2014 survey, illustrating the high desert terrain of Yuma County. The map is defined by a series of critical water catchments and topographical landmarks essential for navigation and survival in this arid landscape. Notable features include Slumgullion Pass and distinctive peaks such as Thumb Peak and Thumb Butte. The presence of several named tanks, including Castle Rock Tank, Blue Rock Tank, Chain Tank, and Red Tank, suggests a history of livestock management or wildlife support in a region where surface water is scarce. Drainage patterns are represented by features like Gravel Wash and Tinaja Seca, which channel seasonal runoff through the desert basins.
