2018 Map of Slumgullion Pass

About this map

Slumgullion Pass provides a natural corridor through the northern reach of the Castle Dome Mountains in this 2018 survey of Yuma County. The arid landscape is defined by dramatic elevation changes between the sharp relief of Thumb Peak and Thumb Butte, and the desert floor drainage patterns. Seasonal watercourses like Gravel Wash and Tinaja Sega cross the quadrangle, illustrating the complex alluvial systems characteristic of the region. This modern topographic record maps the intersection of several townships, including t4s r18w and t5s r18w, documenting the precise physical geography and relief of the Arizona desert during the early twenty-first century.
