Blaine County, Montana

Blaine County is where the high plains of north-central Montana stretch toward Saskatchewan, Canada. It’s Big Sky Country at its finest. Chinook serves as the county seat and sits along the Milk River, which provides an important lifeline for local farmers and ranchers.

The county is home to part of the Fort Belknap Indian Reservation, where the Gros Ventre and Assiniboine tribes maintain their rich cultural heritage. You’ll also find some of the best walleye fishing in the state at Fresno Reservoir.

History lovers can explore the remnants of old frontier forts and homesteads. Blaine County isn’t flashy or famous, but it has a quiet beauty all its own. For those who love wide-open spaces, it’s hard to beat.
