HistoryA character grade: shown, never part of Rock Springs’ 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 Rock Springs’ 0.0 sits below most of its state (28% of New Mexico towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share is a Census survey estimate (±4.9 points).

What stands out about Rock Springs’ past
Read from the archive, the National Register and the record. The page puts what stands out first.
The Rock Springs Chapter started to take form in the late 1930s. It is part of the "Checker Board Area" in the Eastern Agency of the Navajo Nation. The chapter area covers the communities of Sagebrush, China Springs, and Rock Springs. The community of Yatahey Junction (including Navajo Estates) is within the chapter boundaries, although is not governed by the chapter. The chapter is within commuting distance of Gallup and is influenced by this city in terms of modernization.
