Story lies three miles to the southwest, and the Bighorn Mountains (and Bighorn National Forest) are to Banner's west. The town is accessible via U.S. Route 87 (cosigned with Wyoming Highway 193).
The Bozeman Trail passed by town in the mid-1860s. Two important battles of the war between the United States and the Plains Indians happened nearby. The 1866 Fetterman Fight was a victory of the Lakota, Cheyenne, and Arapaho Indians over soldiers of the United States army, and the 1867 Wagon Box Fight involved Lakota Sioux and soldiers from nearby Fort Phil Kearny.[4]
There was an oil spill of the Conoco Seminoe Pipeline near Banner on June 27, 1997.
