Note: At least two photographers, Salt Lake City photographer Charles Roscoe Savage in December 1867, June 1868, and July 1874, and Silver City, Idaho, photographer John Junk in June 1868 took pictures of Shoshone Falls prior to Timothy H. O'Sullivan, who as photographer of the US Army Corps of Engineers took pictures in September–October 1868 and November 1874. Also, there are at least two unattributed early photographs of Shoshone Falls suggesting that there might have been other pioneer photographers.
