This site commemorates one of the last armed efforts of the Northern Plains Indians to preserve their way of life against the encroachment of white civilization. On June 25-26, 1876, 263 soldiers and personnel of the 7th Cavalry were killed by an overwhelming number of Lakota, Cheyenne and Arapaho warriors. Among the dead was Lt Col George Armstrong Custer.
Facilities at the battlefield include a visitor center, museum, the Custer National Cemetery, and the 7th Cavalry Memorial.
The battle is reenacted each June. The site is 15 miles south of Hardin on Interstate 90.
