HistoryA character grade: shown, never part of Rainier’s overall grade.
Few Washington towns list much on the Register (a typical Washington town has 0.1 per 10,000 residents, the U.S. 2.4), so Rainier’s 4.1 sits above most of its state (74% of Washington towns have fewer) while its 1 listings outnumber those of 51% 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 is a Census survey estimate (±7.1 points). The founding year is the first post office, not a stated founding date.

Rainier is situated in an area known as the Tenalquot Prairie. Known also as "Te-nal-cut", "Ta-nal-cuth", or "Ten-al-quelth" to indigenous people in the area, the word most likely means "the best yet" or "happy land" in the Lushootseed language. Another possible meaning is that of a mink in search of home in a human settlement.
By the 1840s, the prairie was used for sheep farming station under the Puget Sound Agricultural Company. Rainier began in the 1870s as a "Prairie Line" stop on the Northern Pacific Railroad track between Kalama, Washington, Tenino and Tacoma. In 1884, the town was named for its view of Mount Rainier.

The Rainier post office opened in 1890, the earliest record of the town by name (U.S. post office records).
