C−
HistoryA character grade: shown, never part of Chinle’s overall grade.
Few Arizona towns list much on the Register (a typical Arizona town has 0.1 per 10,000 residents, the U.S. 2.4), so Chinle’s 7.2 sits above most of its state (76% of Arizona towns have fewer) while its 3 historic buildings outnumber those of 65% 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 (±2.0 points) is firm at this size. The founding year is the first post office, not a stated founding date.

What stands out about Chinle’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
In the Spanish colonial period, Chinle was a base for both trade and war. After acquisition of this area by the United States following the Mexican–American War, relations between the peoples deteriorated in the 1860s.
The United States conducted a peace conference through their representative Kit Carson and the Navajo people in order to end the war between the Navajo and the U.S. The first trading post operated out of a tent and was established here in 1882. By 1885 a full-sized camp had developed.
