The Yellowstone Expedition of 1876, organized to quell the hostile Sioux, marched from Fort Abraham Lincoln on May 17, 1876, and camped a short distance to the south of this site on May 19, 1876. The trail extends to the banks of the Little Big Horn River in Montana, where Custer and a portion of the 7th Cavalry were annihilated by hostile Indians on June 25, 1876. About a mile west of New Salem, the trail of Custer’s Cavalry intersects this highway and continues in a general westerly direction, entering Montana near Beach, North Dakota.
