The Photographs of the Natural Resources Conservation Service, Colorado Snow Survey Program consists of slides, photographs, and films dated 1951 to 1996, with the bulk falling from 1964 to 1991. The collection includes images of snow survey sites and equipment, agency employees, and public outreach events. The majority of locations depicted are in Colorado's Rocky Mountains; however, there are also images of New Mexico and major dams along the Colorado River. Approximately a quarter of the slides are labeled with names of places or people. Two sets of slides are presentations with accompanying audio narration.
