2011 Map of Sierra Arida

About this map

Sierra Arida dominates the arid landscape of this borderland region between Arizona and Sonora as documented in 2011. This sparsely populated terrain is defined by its drainages and isolated water sources, which are essential for survival in such an environment. Water management is evidenced by the inclusion of Sinita Tank and Tuseral Tank, points that likely serve as vital landmarks for those traversing the desert. The presence of these named tanks alongside a few unpaved roads and trails suggests a landscape primarily used for limited ranching, border monitoring, or seasonal passage rather than permanent settlement.
