The University of Nevada, Las Vegas Arboretum Project Records are comprised of documents, brochures, and photographs dating from 1976 to 2012 documenting both the creation and operations of the Arboretum at the University of Nevada, Las Vegas (UNLV). The collection includes photographs of planning the Arboretum, the opening ceremony, and aerial photos of the UNLV campus. The brochures include guides to the Arboretum, lists of types of plants grown, and information on the Xeric Garden.

The C. C. (Clio Cline) Mobley Photograph Collection (approximately 1911 to 1917) consists of sixteen black-and-white photographic prints with corresponding photographic negatives. The images depict the Las Vegas, Nevada Ranch while the Mobley family leased it from the Union Pacific Railroad during the period. The photographs depict the home, swimming pool, the Old Las Vegas Mormon Fort, and orchards and streams on the property.

The Sadie and Hampton George Papers (1874-1948) consist primarily of the incoming and outgoing correspondence of Sadie Kiel George and her husband, Hampton George, regarding proposed land and mineral rights sales. The collection also includes some personal correspondence, and two of the most significant letters in the collection deal with the deaths of brothers William and Edward Kiel, Sadie's uncles, who were found dead at the Kiel Ranch in October 1900. Also included in the collection are receipts, cancelled checks, tax notices, mining claims, and land deeds.
