Alexander Gardner took some of our most important photographs of the Civil War and the 19th-century West. His images from the crucial 1868 treaty negotiations at Fort Laramie capture Sioux, Crow, Northern Cheyenne and Arapaho people, mixed-race families and interpreters, government peace commissioners and vivid scenes of life at the fort.
In the spring of 1878, about 950 Northern Arapaho people arrived with a military escort on the Eastern Shoshone Reservation in the Wind River Valley in central Wyoming Territory. The two tribes had been in open warfare as recently as four years before, and bad feelings lingered between them.
