1978 Map of Negra SW

About this map

The Atchison Topeka and Santa Fe railroad cuts across the northern edge of this high-plains landscape in Torrance County, representing a critical transportation corridor through central New Mexico. The terrain is characterized by subtle elevation changes and a notable Depression in the southeast corner, typical of the sinkhole or playa formations found in the Estancia Basin. Mapped during the late 1970s, this survey focuses on a largely open rangeland area where the infrastructure is limited to basic transport routes and sectional fencing, illustrating the expansive, undeveloped character of the high desert before modern expansion.
