2023 Map of Grandmother Mountain West

About this map

Grandmother Mountain dominates the high desert landscape of the southwest, rising above a network of ephemeral water sources and rugged canyons. The area is defined by its drainage systems, including Walnut Creek in the north and the broad reaches of Flat Canyon to the south. Human activity in this arid environment is evidenced by essential water catchments like Big Tank, Barksdale Tank, and Bentley Tank, which support the region's ranching heritage. The map also delineates the boundary between Grant County and Luna County, showing how political lines bisect the natural terrain of Cow Springs Draw and China Draw. This modern topographic study provides an exact look at the land's relief, from the peak of Grandmother Mountain down to the lowest reaches of Hay Draw.
