The campus of Washington State University (including campus architecture, sporting events, campus activities, and administrators) is extensively documented, as is the city of Pullman and the surrounding Palouse communities. The collection records the changes on the campus of WSU and in rural communities between the 1920s and the 1970s. Agricultural photographs trace the shift from the use of horses in harvesting to modern combines. New technologies are also represented: the arrival of the first model T, the introduction of electric washers and dryers, people standing proudly by their new home freezers and air-conditioners. Though many of the photographs depict the town and farms of the Palouse region of southeastern Washington and northern Idaho, neighboring geographic areas are also represented. These include the Columbia River gorge, the heavily forested areas of northeastern Idaho and the semi-arid deserts of central Washington. In addition to the campus of WSU and wheat farming, there are scenes of pea processing, logging, shipping, and construction.
