HistoryA character grade: shown, never part of Douglas City’s overall grade.
Few California towns list much on the Register (a typical California town has 0.0 per 10,000 residents, the U.S. 2.4), so Douglas City’s 0.0 sits below most of its state (31% of California 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 (±1.9 points) is firm at this size. The founding year is the first post office, not a stated founding date.

What stands out about Douglas City’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The prehistoric residents of the area were Wintun people; from North Fork to Douglas City the group was called Tien-Tien which means "friends". The Karuk called the same people the Kashahara. Local people suffered loss of population beginning with the epidemic of 1842. The explorer Jedediah Smith and his party came through the Hayfork area in 1828, killing several local people to intimidate the others and permit their passage. The Tien-Tien population was further reduced during the gold rush along the Trinity River.
The Douglas City post office opened in 1859, the earliest record of the town by name (U.S. post office records).
