The two scrapbooks, which cover 1948-1957 and 1962, consist of newspaper clippings, photographs, flyers, sample newsletters, and ephemeral items documenting the club's skiing, mountaineering, and rescue activities, as well as activities of the club's current and former members.
The constitution probably dates from the early 1960s. Meeting minutes date from 1947-1950, 1953-1954, and 1967-1969. Holdings of the club's newsletter, the Local Yodel, are from 1949-1952, 1954, 1962, and 1967-1971. Many of the issues from 1949-1952 are located in the first scrapbook. The Mountain Rescue Association materials (1959-1975) include correspondence, Corvallis Unit member lists, photographs of practice rescues and other information.
The miscellaneous materials include correspondence between Willi Unsoeld, Barry Corbett, and others regarding a mountaineering film Corbett was planning (1959-1960); and annual organization review forms from the Student Activities Committee (1971/72-1973/74).
