2014 Map of Butler Mountains

About this map

Yuma Desert sands and the arid expanse of Davis Plain dominate this landscape along the international boundary between the Arizona border and Sonora, Mexico. The topography is defined by the sharp elevations of the Butler Mountains and the western edge of the Tinajas Altas Mountains, which rise abruptly from the surrounding desert floor. This 2014 survey documents the precise path of the international border as it cuts diagonally across the quadrangle, passing through Yuma County. The map provides a clear record of the section lines and township boundaries, including t13s r19w and t12s r18w, illustrating the intersection of modern political boundaries with the natural landforms of the Sonoran region.
