2014 Map of Cumero Mountain

About this map

Coronado National Forest dominates the upper half of this 2014 survey, where the rugged southern Arizona landscape meets the international boundary line with Mexico. The terrain is defined by the San Luis Mountains and prominent peaks like Cumero Mountain and Lesna Peak. Industrial and water-management features are scattered throughout this arid environment, most notably the Sandwash Mill and a series of livestock tanks such as Slick Rock Tank, Alamito Tank, and the curiously named Marijuana Tank. Below the border, the topography levels into a grid, while the northern portion remains a network of ephemeral drainages like Arrieta Wash and deep cuts like Coches Canyon. This map provides a clear record of the ranching and milling infrastructure existing along the Pima Co border in the early 21st century.
