1996 Map of Tinajas Altas

About this map

The Tinajas Altas Mountains dominate this arid borderlands survey, defining a stark corridor between the Lechuguilla Desert and the Davis Plain. Mapping across the international boundary with the United States of America Estados Unidos Mexicanos, the sheet captures the remote topography of Yuma County and the northern reaches of the Desierto de Altar. Historically significant water sources like Tinajas Altas and the Surveyors Tank provide critical reference points in a landscape largely utilized by the Barry M Goldwater Air Force Range. The map reflects a complex administrative intersection where military reservation lands meet the high desert of Arizona Sonora, illustrating the transit paths through Coyote Wash and the surrounding terrain prior to the twenty-first century.
