HistoryA character grade: shown, never part of Alamogordo’s overall grade.
New Mexico towns list about as much on the Register as the country (a typical New Mexico town has 2.2 per 10,000 residents, the U.S. 2.4), so Alamogordo’s 2.2 sits near the middle of its state (62% of New Mexico towns have fewer) while its 7 listings outnumber those of 73% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C− to B−. The pre-1940 share (±0.8 points) is firm at this size. The founding year is the first post office, not a stated founding date.

Tularosa Basin has been inhabited for at least 11,000 years. There are signs of previous inhabitants in the area such as the Clovis culture, the Folsom culture, the peoples of the Archaic period, and the Formative stage. The Mescalero Apache were already living in the Tularosa Basin when the Spanish came in 1534, and Mescalero oral history says they have always lived there. In 1719, the Spanish built a chapel at La Luz (about 5 miles (8.0 km) from the future site of Alamogordo), although La Luz was not settled until about 1860.
