The Frances Intravia Photograph Collection (approximately 1948 to 1979) contains three black-and-white photographic prints. The images depict Albert and Arabell Lee Hafner, author of 100 Years on the Muddy, visiting the St. Thomas, Nevada townsite after the Lake Mead water levels dropped enough make it visible. One of the prints is an original from approximately 1948 to 1952, and the other two are reproductions of images taken during the same period.
