HistoryA character grade: shown, never part of Tieton’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 Tieton’s 0.0 sits below most of its state (27% of Washington towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D to C. The pre-1940 share is a Census survey estimate (±5.9 points). The founding year is the first post office, not a stated founding date.

What stands out about Tieton’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Tieton was officially incorporated on June 5, 1942. The city's name is derived from the Tieton River, meaning "roaring water".
The city's economy was primarily agricultural and its largest employers were cool warehouses for fruit that was grown in the Yakima Valley. In 2007, a Seattle lawyer and the founding president of the art publishing house Marquand Books began to finance a revitalization plan, named "Mighty Tieton", to bring new industries to the area. Among the initiatives was the creation of a mosaics studio that began to produce new artwork that would be displayed in Tieton.
The Tieton post office opened in 1909, the earliest record of the town by name (U.S. post office records).
