The Guy Weyer Miller and Jeannette Bonar Miller Mendenhall Glacier and Mount Rainier Slides are 23 slides of color photographs taken of Mendenhall Glacier and Mount Rainier in August 1962. There are 11 slides of Mendenhall Glacier and 12 slides of Mount Rainier. Two USB flash drives, dated 2016, contain scanned images of the original slides. The images of Mendenhall Glacier depict close up shots of the glacier, the visitor's center, the surrounding landscape and plants, and a faraway image of Jeannette Miller. The images of Mount Rainier depict the mountain and one of its lakes, two photographs of Guy and Jeannette Miller with the mountain in the background, and a aerial view of the mountain.

The Color Slides Made From Photographs Taken by Scott Fischer During 1994 Ruth Glacier Expedition is a binder that contains approximately 800 color slides. The slides are dated July 8 and 19, 1994. Some slides contain a caption with someone’s name or the location of the photograph. The photographs primarily feature Ted Heckathorn and the Ruth Glacier Expedition team traversing the Ruth Glacier and Mount Denali. Photographs of Mount Denali’s landscape are also included. There is a note attached to a slide page that identifies three photographs of Scott Fischer.
