About Beaverhead County
With an average elevation of over a mile, Beaverhead County sits in the southwestern corner of Montana. Much of its boundary is formed by the Continental Divide. Encompassing an area slightly larger than the state of Connecticut, Beaverhead is the largest county in Montana. However, Beaverhead County is sparsely populated. It ranks 25th of Montana’s 56 counties, having an average population density of less than 1.7 people per square mile. This sparseness in population can be attributed to nearly 2/3 of the land being comprised of public lands including the Beaverhead Deer-Lodge National Forest, Red Rocks Lakes National Wildlife Refuge, Bureau of Land Management and State Lands.
