Little Bighorn River mouth of the Little Bighorn canyon there is a gravel road maintained by Bighorn County. However, from the point at which the river flows out of the canyon (at about the Wyoming-Montana state line) the road continues upstream in the canyon for only about 2 miles. There are two (and sometimes three) unbridged stream fords. This portion of the road is unmaintained and is a two track road with tight turns. It is primitive, rough, ungraded, and littered with partially buried boulders. When it rains large puddles accumulate in low spots. It is impassible in the winter after snow accumulates
Battle of the Little Bighorn in a series of conflicts known as the Sioux Wars, which took place from 1854-90. While some of the indigenous people eventually agreed to relocate to ever-shrinking reservations, a number of them resisted, at times fiercely. On May 7, 1868, the valley of the Little Bighorn became a tract in the eastern part of the new Crow Indian Reservation in the center of the old Crow country. There were numerous skirmishes between the Sioux and Crow tribes so when the Sioux were in the valley in 1876 without the consent of the Crow tribe, the Crow supported the US Army
