From 1887 to 1892 John CH Grabill sent 188 photographs to the Library of Congress for copyright protection. His photos capture the ending of the Old West featuring landscapes and people mostly of the Dakotas, often of the town of Deadwood and the Pine Ridge Indian Reservation. A sampling is below and it is worth looking at the collection at angelfire.com (via Never Yet Melted).
The Pine Ridge photos are from an area just north of Sheridan County, Nebraska featured in a prior THC post and only an hour drive away from Carhenge.
