B+
HistoryA character grade: shown, never part of Kamiah’s overall grade.
Idaho towns list more on the Register than most of the country (a typical Idaho town has 8.4 per 10,000 residents, the U.S. 2.4), so Kamiah’s 36.9 sits above most of its state (82% of Idaho towns have fewer) while its 4 listings outnumber those of 68% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B to A. The pre-1940 share is a Census survey estimate (±8.6 points). The founding year is the first post office, not a stated founding date.

What stands out about Kamiah’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The Kamiah area has been inhabited by the Nez Perce for centuries. The name "Kamiah" is Nez Perce for "many rope litters," as Nez Perce manufactured "Kamia" ropes in the area to fish steelhead. Also according to Nez Perce tradition, the Appaloosa horse was first bred in the area.
On their return trip east, the Lewis and Clark Expedition camped in the Kamiah area for several weeks during the spring of 1806, waiting for snows to melt.
