The Gene Hertzog Professional Papers (approximately 1930-2015) are comprised of photographs, slides, transparencies, publications, video cassettes, correspondence, and digital files spanning Gene Hertzog's working years with the United States Army, the Bureau of Reclamation, and as a freelance photographer and videographer based in Southern Nevada, New Mexico, and Washington state. The collection documents the complicated infrastructure required to supply water to the Las Vegas Valley and includes still and moving images of the Springs Preserve, Lake Mead National Recreation Area, the Colorado River, and the Columbia Basin. The majority of the collection comes from Hertzog's time as a regional photographer for the Bureau of Reclamation and offers a unique glimpse into the Bureau's work in Southern Nevada, the southwest, and the Pacific Northwest from the 1950s to the mid-1990s.

The Harry Hayden Whiteley Photograph Collection (approximately 1940-1967) contains photographic prints and one photographic negative depicting buildings, people, and project locations associated with the Las Vegas, Nevada architect Harry Hayden Whiteley. There is also one album containing photographs of contemporary churches compiled by Whiteley between 1953 to 1958.
