What drives Big Bear Lake’s History grade
On its age, its old homes and the National Register, Big Bear Lake is more historic than 13% of U.S. towns, #619 of 847 in California. Its share of homes from before 1940 holds the grade up; its age pulls it down.
D
HistoryA character grade: shown, never part of Big Bear Lake’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 Big Bear Lake’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 (±1.3 points) is firm at this size. The founding year is the first post office, not a stated founding date.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

What stands out about Big Bear Lake’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Big Bear Lake was inhabited by the indigenous Serrano people for over 2,000 years before it was explored by Benjamin Wilson and his party. Once populated by only the natives and the grizzly bears, from which the area received its name, the population of the Big Bear Valley grew rapidly during the Southern California gold rush from 1861 to 1912. Grizzly bears were not found in the region after 1908. Black bears have been in the region since their introduction in 1933, and they are sometimes sighted in residential areas.
