An extensive flat mesa bounded on the west by the Otero Escarpment and on the north by the Sacramento Mountains. The habitat is almost exclusively Chihuahuan Desert grassland with some shrubland. A large part, McGregor Range, is managed by Ft. Bliss under withdrawal from the BLM. This is used for grazing as long as it does not interfere with military activities resulting in McGregor Range being in good condition. BLM owns most of the mesa to the east of McGregor Range although some is privately held. The BLM lands have great potential for prairie dogs and all associated fauna and grassland birds.

Directions: From US-54 between Alamogordo and El Paso, turn east on NM-506. Numerous dirt and gravel roads go through various parts of the mesa.
