2011 Map of Monument Bluff

About this map

Monument Bluff rises as the primary landmark in this arid stretch of the Arizona-Sonora borderlands. This 2011 survey by the U. S. Geological Survey details a landscape defined by an intricate network of desert washes and drainage patterns that carve through the basin. Positioned along the international boundary between Arizona and Sonora, the map illustrates the stark topography of the region, where the terrain slopes toward the southwest across the border into Mexico. The absence of modern development or named settlements underscores the isolated nature of this desert environment, focusing instead on the natural landforms and the subtle elevation changes that define the corridor between the United States and Mexico.
