Lodge Grass, on the Little Bighorn River and the Crow Indian Reservation, is a center for ranches whose herds graze the rich, grass-covered uplands where buffalo used to range. Long ago the Crows made their summer camps here. The town was named for Lodge Grass Creek, which empties into the Little Bighorn. The Indians called the stream "Greasy Grass" because the rich grass made their animals fat. The words "grease" and "lodge" are so similar in the Crow language it translated into Lodge Grass.
