2020 Map of Dewey

About this map

The Big Hole River winds along the southern edge of this montane landscape, marking the historical border between Silver Bow and Beaverhead counties. The settlement of Dewey sits on the river's northern bank, serving as a primary point of human activity in an area otherwise dominated by the high-elevation reaches of the Deerlodge and Beaverhead National Forests. Local history is anchored by the Dewey Cem and a network of named drainages like Nez Perce Gulch and Sheep Gulch that hint at early land use and migration patterns through these peaks.
