The Harold Frodsham Photographs consist of 19 images taken by Frodsham of the interiors and exteriors of lumber mills in Oregon during a tour of mills in Oregon and northern California. The prints are 3.5 x 5.5 inches and are annotated with detailed descriptions. There are duplicate prints for two of the images. The collection includes images of the Booth-Kelly Lumber Company (Springfield), Brooks-Scanlon Lumber Company (Bend), Pelican Bay Lumber Company (Klamath Falls), Shevlin-Hixon Company (Bend), and Silverton Lumber Company (Silverton). The photographs depict hauling equipment, stackers, and conveyors. The collection also includes one image of Brooks-Scanlon Lumber Company Camp 1 in central Oregon where Ponderosa pine is being logged.
All of the images are available online in the Oregon Explorer Digital Collection of historic photographs.
An addition to the Frodsham Photographic Collection (Accession 2011:013) is made up of 21 images taken by Frodsham of operations at the Red River Lumber Company (Westwood, California) and the Hutchinson Logging Camp (Oroville, California). Most of the photographs in this transfer document the construction of a power plant along the Feather River for the Red River Company.
