The Blue Mountain Chorus records contains the scrapbooks, photographs, recordings, programs, promotional materials, awards, and scripts produced by members of the Walla Walla-based Blue Mountain Chorus, a women’s barbershop chorus and social group, from 1973 to 2016. Although most of the materials reflect the members' performances and social activities, the collection may also be of interest to those researching prominent people in the Walla Walla area.
