2021 Map of Tinajas Altas

About this map

The Tinajas Altas Mountains dominate this borderland landscape, where the jagged peaks meet the sweeping expanse of the Lechuguilla Desert and the Yuma Desert. This modern survey documents a critical junction of geography and history along the international boundary, capturing the stark transition from the mountain slopes to the open flats of Davis Plain. Central to the area's significance is the Tinajas Altas Pass and the eponymous Tinajas Altas water source, a legendary stop for travelers in this arid region for centuries. The map details the drainage patterns of Coyote Wash and the complex topography that historically dictated the routes of travel across the Sonoran landscape before reaching the southern international line.
