About this map

Little Borrego sits at the northwestern edge of this 2015 survey, where a grid of streets including Broadway and Main ST meets the open desert. The landscape is defined by the transition from the arid floor of the Lower Borrego Valley to the surrounding peaks. The Vallecito Mountains rise in the southwest, while the Fish Creek Mountains dominate the southeastern quadrant. This topography creates a complex network of drainage features, including the braided paths of Fish Cr Wash, Alma Wash, and San Felipe Cr.

Tracing the historical infrastructure of the region reveals routes such as Old Kane Spring Rd and Old Mine Rd, which hint at the area's developmental history. Near the town site, Halfhill Lake provides a rare point of standing water in this desert environment. The presence of Split Mountain Rd leading toward Split Mtn highlights the importance of geological landmarks for navigation in the expansive San Diego and Imperial County borderlands.
