The accession includes correspondence, biographies, bibliographies, awards, degrees, maps, manuscripts, memoranda, photographs, publications, notebooks, reprints, newspaper clippings and other material documenting Dietz's career. The Subject Series include material on creationism, continental drift, geomorphology, Meteor Crater, Sudbury Basin (Ontario, Canada), meteoric impacts, plate tectonics, TRIESTE, and Trou San Fond Submarine Canyon in Ivory Coast. The files include a few file folders on Project Mohole and two file folders on Dietz's teacher Francis P. Shepard. The collection included Rival File boxes which contained original manuscript and reprints of Dietz's publications and a Bible, which was heavily annotated and included a great deal of marginalia in Dietz's hand. The annotations and marginalia suggest that the Bible was used in connetion with Dietz's interest in creationism. The files also include information on Soviet oceanography.
