2020 Map of Shannon Canyon

About this map

The San Andres Mountains dominate the eastern reaches of this Sierra County landscape, giving way to a complex network of high-desert drainages and canyons. The terrain is defined by dry washes like Big Pitch Draw, Brushy Draw, and Waterhole Draw, which illustrate the arid hydrology of south-central New Mexico. Settlement here is sparse and focused on water management, evidenced by distributed infrastructure such as Hardin Tank, Middle Tank, and South Tanks. Named topographical features like Shannon Canyon and Well Canyon provide the primary landmarks for navigation through the township and range divisions. The map also traces local travel routes including Walker Loop and several county roads such as Co RD A-26, providing a record of the rural road network used for ranching and resource access.
