Note: These images are National Archives photos (courtesy of the Gallery of the Open Frontier) dating from the 1860s through the 1890slong after the Corps of Discovery passed through the homelands of the Native nations that are depicted. The images are included to give a sense of the vibrancy and enduring nature of the Native cultures the expedition encountered. Despite many far-reaching and often tragic changes that occurred in the decades following the Corps of Discovery's travels, these cultures persisted. The images do not, of course, represent actual individuals or villages encountered by the expedition.
