The story so far

from Wikipedia & the U.S. Census

Dewey is an unincorporated community and census-designated place (CDP) in Beaverhead County, Montana, United States. It is in the northeast part of the county, on the south side of the Big Hole River, and bordered to the north, across the river, by Silver Bow County. Montana Highway 43 passes through Dewey, leading east 7 miles (11 km) to Interstate 15 at Divide, and west up the Big Hole River valley 5.5 miles (8.9 km) to Wise River and 44 miles (71 km) to Wisdom. As of the 2020 census, Dewey had a population of 25. Dewey was first listed as a CDP prior to the 2020 census.

Half of its homes were built before 1976.

Wikipedia doesn’t have a history of Dewey yet — the old photos, dates and memories neighbors add here are how it gets written.

Nothing in Dewey is on the National Register yet

That’s true of most small towns. It doesn’t mean Dewey has no history, only that no one has written up a nomination. The closest listed place is Big Hole Pumpstation in Butte-Silver Bow, 3.2 miles away.

How a place gets listed

1Talk to the stateEvery nomination goes through the State Historic Preservation Office. Owners, towns and historical societies can start one.
2Try a local or state list firstMany states keep their own register with a shorter form, a common first step for old barns, halls and schoolhouses.
3Write it upA nomination covers the history, photos and a map. Big Hole Pumpstation’s page links to a real one.
