In 1862 they joined the Hidatsa and Mandan at Like-a-Fishhook Village, near the Fort Berthold trading post. For work, the Arikara men scouted for the U. S. Army, stationed at nearby Fort Stevenson. In 1874, the Arikara scouts guided Custer on the Black Hills Expedition, during which his party discovered gold. This resulted in a rush of miners to the area, causing conflict with the Lakota, who considered the Black Hills to be sacred.
