Collection includes 98 lantern slides, some hand colored, collected by William F. Hanson. The slides include images of the Ute Indians of Colorado and Utah, scenes from Hanson's operas, and nature scenes.

Indian opera productions composed by Hanson, musical scores, research material, and scrapbooks and photos based on ceremonies and music of the Ute Indians of Colorado and Utah. Operas included are: "Sun Dance," produced in New York City, 1938, "Bear Dance," and "The Bleeding Heart," a white man's fantasy of an imaginary Indian people who lived at the base of Mount Timpanogos in Utah.

This collection contains 65 photographs and 102 negatives (and prints from those negatives) from William F. Hanson. Most of the photographs and negatives are duplicates of material found in the William F. Hanson Papers (MSS 229) and the William F. Hanson Collection (MSS 3340). The images are mainly of Indian opera productions composed by Hanson and of the Ute Indians of Colorado and Utah, as well as several photographs of William F. Hanson himself.
