2018 Map of Cumero Mountain

About this map

The United States of America Estados Unidos Mexicanos international border defines the southern extent of this 2018 survey, where the high desert terrain of Pima County meets the San Luis Mountains. This landscape is a patchwork of conservation and resource management, split between the Buenos Aires National Wildlife Refuge to the west and the Coronado National Forest to the east. Historically, the area supported mining and ranching, evidenced by the centrally located Sandwash Mill and a network of water catchments like Slick Rock Tank and Lesna Spring. Prominent peaks such as Cumero Mtn and Lesna Peak rise above deep drainages including Arrieta Wash and Coches Canyon. The map provides a detailed view of the infrastructure supporting this arid environment, from the Garcia School Rd to the remote Cantina Reservoir near the international boundary.
