The Wayne Cronister Photograph Collection depicts towns in Southern Nevada from 1905 to 1950. The photographs primarily depict Fremont Street in Las Vegas, Nevada and the construction of the Hoover (Boulder) Dam on the Colorado River. The photographs also include the Union Pacific Railroad Depot in Las Vegas, Nevada, the abandoned town of Rhyolite, Nevada, and a mining camp in El Dorado Canyon.

The Joseph C. Ives Personal Correspondence consists of seventeen photocopied letters between United States Army Corps of Topographic Engineers Lt. Joseph C. Ives and his wife, Cora Semmes Ives, between September 1857 and June 1858. Ives was in command of a U.S. Army expedition whose mission was to explore the region of the Colorado River and the Grand Canyon, and to establish the limit of navigation of the Colorado River. The correspondence is largely personal in nature, however, it is a useful supplement to the official report documenting the voyage, "Report upon the Colorado River of the West; Explored in 1857-1858."
