The Barbara and John Kizziar Photograph Collection primarily contains black-and-white photographic prints and negatives of Hoover Dam (Boulder Dam) construction during John Kizziar’s time working for Six Companies Inc. between approximately 1986 and 1992. These images are reproductions of originals taken from between approximately 1930 and 1945. They detail John Kizziar’s work life during the dam’s construction, as well as events and scenes associated with the dam. Other images portray billboards and streets in Boulder City, Nevada. The collection also depicts other locations in Nevada, including Las Vegas, Mount Charleston, Black Canyon, the northern Mojave Desert, and the Colorado River ferry crossing between Nevada and Arizona.
