2017 Map of Summit

About this map

Summit Hills and the southern reaches of the Animas Valley define this landscape in Hidalgo County, where water management is the primary marker of human activity. The settlement of Summit sits at the head of Railroad Wash, illustrating how early infrastructure followed natural drainage patterns in the high desert. A network of ranch roads, including Double M Ranch Rd and Rafter J L Ranch Rd, connects scattered livestock watering points like High Lonesome Tank and Three Mills Tank. This 2017 survey reveals a ranching economy still reliant on these isolated improvements, with named landmarks like Summit Tank and Road 4 Tank serving as essential nodes in the arid terrain. The map provides a precise view of public land survey sections and ranch boundaries that have structured this corner of New Mexico for generations.
