The Tinajas Altas Mountains dominate the center of this remote desert landscape along the international boundary between the United States of America and Mexico. The terrain is defined by the sharp transition from the elevated peaks to the surrounding lowlands of the Lechuguilla Desert to the east and the Yuma Desert to the west. Rare water sources in this arid environment are critical landmarks, including the namesake Tinajas Altas and Surveyors Tank. The map also highlights the strategic Tinajas Altas Pass, a gap through the range that historically facilitated movement across the Davis Plain. This survey provides a detailed look at the borderlands within Yuma County, where the geography remains largely untouched by development, focusing instead on natural features and elevation.
