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
Little Bighorn River turn, would wet moccasins and leggings of Indian people, and the bellies and legs of horses, and cause them to look greasy. On the main stream, the name Greasy Grass slowly gave way to the name Little Bighorn. For one major tributary of the Little Bighorn, the (presently named) Lodge Grass Creek retained the name "Greasy Grass Creek", but as Joe Medicine Crow explained in the 2012 video, this name morphed from "Greasy Grass" to "Lodge Grass" due to the error of an interpreter since the Crow word for "greasy" is Tah-shay, and the Crow word for "lodge" is Ah-shay.
