This historic site preserves the valley where, in late 1864, a large group of Cheyenne and Arapaho people was attacked while camped along Big Sandy Creek. Leaders such as Black Kettle had been seeking a path to peace when the violence occurred. The events remain a painful memory for Native American communities. Reaching the site involves driving on unpaved roads near the town of Eads, and the National Park Service offers ranger-led stories and educational programs.
