The Great Plain dominates the northern reaches of this borderlands survey, where the arid landscape of southern Pima Co, Arizona, meets the international boundary. This portion of the Sonoran Desert is defined by the stark diagonal of the United States of America Estados Unidos Mexicanos border line, cutting across the natural terrain. The map illustrates a transitional zone where the flat expanses of the desert floor begin to yield to subtle topographic changes, mapped through a series of north-south dry washes and drainage patterns that characterize the local hydrology. This 2014 edition provides a clear record of the political and geographic dividing line at a specific point in the early 21st century, showing how the public land survey system intersects with the sovereign border.
