Treasure County, Montana
Treasure County is located in southeastern Montana. It’s the second least populous county in the state, so blink and you might miss it.
The Yellowstone River runs through the heart of the county, creating a lush valley amid the dry plains. Hysham is the only real town and serves as the county seat.
Ranching is king here, with cattle far outnumbering people. The Big Sky feels even bigger across this wide-open landscape. Despite its small size, Treasure County captures Montana’s spirit of rugged independence and strong community.
