The San Augustin Mountains are a small mountain subrange located at the southern terminus of the San Andres Mountains east of Las Cruces, New Mexico.

Description

The San Augustin Mountains are only about an 8 mi long range, trending slightly northeast. The southern border is San Augustin Pass, where U.S. Route 70 goes from Las Cruces and Organ and turns northeast through White Sands to meet Alamogordo. The north of the range is delimited by Bear Canyon, an east-west canyon with its outlet to the northeast. Also north is the San Andres National Wildlife Refuge which takes up about a 30 mi stretch of the San Andres Mountains ridgeline. The high Black Mountain section is on the southeast of Bear Canyon and is separated northeast from the ridgeline of the San Augustins.
