San Agustin sits in the northeastern reaches of the Chukut Kuk District, a landscape defined by an intricate network of ephemeral watercourses typical of the Sonoran borderlands. This 2011 survey illustrates the subtle topographical shifts of the desert floor, punctuated by the elevations of Morena Mountain and Horse Peak. The terrain is characterized by broad alluvial fans and washes that drain the region, showing the sparse but distinct footprint of human presence at the base of these peaks. As a modern record, it provides a precise visualization of the arid basin-and-range geography, preserving the location of small settlements and high points that have long served as landmarks for those navigating this desert environment.
