2014 Map of West of Quitobaquito Springs

About this map

The United States of America Estados Unidos Mexicanos international boundary cuts diagonally across the northern portion of this map, marking the high-desert divide between Pima Co, Arizona, and the Mexican state of Sonora. The landscape below the border is characterized by a dense network of ephemeral desert washes and alluvial fans that flow southward across the open terrain. This survey provides a precise look at the geopolitical line and the drainage patterns of the borderlands during the early 21st century. While the sheet is primarily focused on the topographic and hydrographic features of the desert floor, it clearly delineates the township and range divisions of the Pima Co region, illustrating the formal structure of the American public land system as it meets the international frontier.
