About this map

Lower Borrego Valley is defined by a striking transition from the flat, arid basin floor to the steep elevations of the Vallecito Mountains and Fish Creek Mountains. A grid of platted streets, including Main St and Broadway, sits on the western edge of the quadrangle near the San Diego and Imperial County line, though the surrounding landscape remains largely open. Hydrographic features like San Felipe Cr and Alma Wash provide evidence of the intermittent water drainage patterns that shape this desert environment. Cultural and recreational assets are visible through the Elephant Tree Nature Trl and various desert routes such as Old Kane Springs Rd and Old Mine Rd. The terrain is famously interrupted by the geological formation at Split Mtn, while Halfhill Lake stands as a rare permanent or seasonal catchment in an otherwise high-drainage sector of the valley.
