This image of Rain-In-The-Face has been attributed to the photographer, F. Jay Haynes, and it appears on page 198 of the book 'Following the Frontier' by Freeman Tilden. Although no date is given for the photograph, it was likely taken sometime after Rain surrendered at Fort Keogh in 1880, the same year that Haynes was known to have been photographing various sites in Montana territory. Interestingly, Haynes has also been credited as the photographer for the group shot from Standing Rock, in which Rain holds a copy of this earlier photographic portrait. — Glenbow

Rain In the Face is buried at the Episcopal cemetery in Bullhead/Rock Creek, South Dakota. Another grave at St Bernard's mission has been mislabelled to be Rain in-The Face's Grave. It is really Crazy Walker. — LaDonna Brave Bull Allard

Rain's grave can no longer be located. A dam gave way, and the resulting flood waters washed many graves away. Many bodies (most?) were not found. Rain's grave was one of those washed away. — Tokaouspa

The next portrait we have is the one in the warbonnet by Huffman, 1880-1881?:
