This collection consists of expedition notes, reports, photographs, and field notes. Series 14, "Field Notes, 1930-1942, 1946-1969," are currently located at the National Museum of Natural History, Division of Vertebrate Paleontology. As of March 2012, this record describes only Series 4, "Expeditions, field work and study trips, 1934-1941, 1946-1969, and undated", located at the Smithsonian Institution Archives. This collection contains 46 folders of reports and photographs created approximately 1930 to 1970 from Gazin's time working for the United States Geological Survey and the National Museum of Natural History. Reports typically contain a one page summary of the collecting trip, list of expenses, and list of specimens collected. These field trips were often taken during the summer. Franklin L. Pearce often collected with Gazin during these trips. Most of the trips occurred in the Eocene and Paleocene formations in Wyoming. Other states in which Gazin collected include Idaho, New Mexico, Utah, Montana, Nebraska, Arizona, and Colorado. Gazin also collected in Panama. The photos within this collection depict mostly collecting locations and field work. The unearthing of fossils, creation of field jackets (encasings in plaster and burlap or possibly old bandages), and recreation time of the collectors are examples of events depicted. The following correspondents are included: Secretaries Wetmore, Carmichael, and Ripley; Remington Kellogg; Secretaries of the Interior; Gazin. Gazin's collections are vertebrates, mostly mammals. The specimens are from the following stages: Cretaceaous, middle Eocene, Palaeocene, lower Oligocene, late Wasatchian, and others. He collected in the Bridger Basin (Bridger Formation), Wind River Basin, Green River Basin, San Juan Basin, and others.
