Big Horn County is a county located in the U.S. state of Montana. As of the 2020 census, the population was 13,124. [1] The county seat is Hardin. [2] The county, like the river and the mountain range, is named after the bighorn sheep in the Rocky Mountains. [3] The county was founded in 1913. [4] It is located on the south line of the state.
Most of the area is part of the Crow Indian Reservation. Reservation poverty affects the county, which is the second-poorest county in the state.
On June 25, 1876, the Battle of Little Bighorn began. The Battle is also known as the Battle of the Greasy Grass to the Lakota and other Plains Indians.
