The KLVX Steamboats on the Colorado Photograph Collection contains photographic prints and negatives used by the Las Vegas, Nevada television station KLVX (Channel 10) for a documentary on steamboats in the Southwest United States between approximately 1870 and 1979. KLVX made this documentary for the Arizona American Revolution Bicentennial Commission and the Nevada American Revolution Bicentennial Commission, who jointly funded the documentary’s production. Some of these photographs may be reproductions of originals gathered during the research for the documentary.

Oral history interview with Anna Jennings Welsh conducted by Judith Siu on July 05, 1975 for the Ralph Roske Oral History Project on Early Las Vegas. Welsh begins by describing her family's history in Las Vegas, Nevada, beginning in 1911 with her grandmother. She discusses her grandmother's life and her collection of artifacts, which would later become part of the Southern Nevada Museum by the Henderson, Nevada Chamber of Commerce (now the Clark County Museum). Welsh continues talking about her own life, including her education, hobbies, family, friends, and living in Las Vegas. She also discusses nuclear weapons testing, the history of casinos in Las Vegas, her father's work constructing Hoover Dam (Boulder Dam), and how Las Vegas has changed.
