2020 Map of Greg Hills

About this map

Greg Hills and the winding course of Whiterock Canyon define this high-desert landscape where Grant, Sierra, and Luna counties converge. This 2020 survey documents the complex drainage systems of the southwestern New Mexico backcountry, including the deep incisions of Black Canyon and Macho Canyon. The survival of ranching and transit in this arid environment is written in the sparse water sources like Greg Spring and China Tank, alongside seasonal watercourses such as Macho Cr and Mule Springs Creek. An established network of rural roads, including Macho Rd and White Rock Rd, connects the high ground of the hills to the broad expanse of Chandler Draw in the south, illustrating how terrain dictates movement through this isolated borderlands region.
