Garryowen is on the Little Bighorn River a few miles south of the Little Bighorn Battlefield National Monument and is within the boundaries of the Crow Indian Reservation. The Custer Battlefield Museum is located on the former site of Sitting Bull's camp, on the famous Garryowen bend of the Little Bighorn River, a traditional summer hunting campsite for many Plains Indian tribes. As the Seventh Cavalry approached in late June of 1876, this was the site of one of the largest Indian gatherings ever recorded in North America.
