Big Horn County, Montana
In southeastern Montana, where the plains meet the mountains, lies Big Horn County. It’s a land of contrasts, blending ancient history with modern life. The county gets its name from the Bighorn River, which cuts through its heart.
Crow Agency is home to the Crow Nation’s tribal headquarters, while Hardin serves as the county seat. You’ll also find the Little Bighorn Battlefield National Monument here, marking the site of Custer’s Last Stand.
The Bighorn Mountains rise in the distance, creating a rugged playground for hikers and hunters. Summers are hot and dry, while winters can be brutal. Agriculture drives the local economy, with vast ranches and farms covering the landscape. But for those who call Big Horn County home, the wide-open spaces and big-sky country make it all worthwhile.
