What drives Whitehall’s History grade
On its age, its old homes and the National Register, Whitehall is more historic than 55% of U.S. towns. Its share of homes from before 1940 holds the grade up; its age pulls it down.
B
HistoryA character grade: shown, never part of Whitehall’s overall grade.
Montana towns list more on the Register than most of the country (a typical Montana town has 12.7 per 10,000 residents, the U.S. 2.4), so Whitehall’s 8.7 sits near the middle of its state (47% of Montana towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C to B+. The pre-1940 share is a Census survey estimate (±8.8 points). The founding year is the first post office, not a stated founding date.

Whitehall began as a rail depot created by the Northern Pacific and Montana Railroad on September 25, 1889. The name for the depot came from E.G. Brooke, who was inspired by a similar town in which he stayed in Illinois while making his way westward. On September 3, 1890, the Jefferson County Commissioners accepted and filed the Townsite of Whitehall.
