This collection contains correspondence with W.B. Cook dated January 17, 1941, a bibliography of related resources, 1 map of Mount Shasta, and 19 photographs of Mud Creek Glacier on Mt. Shasta in August and September of 1924. Warmer weather caused a melting of the glacier, sending down the canyon a wall of water, mud, sand, and rock.

All photographs were taken September, 1924. Included in the photographs are 4 enlargements that create a panorama of Mud Creek Canyon - north wall of Mud Creek Canyon. All of the photographs have been cataloged and given a sc number, except for three.
