Paleontological and Geological Investigations in the John Day Region of Eastern Oregon

Abstract

A coordinated program of research, rather unique in the range and detailed nature of the studies included in it, is being conducted in the John Day region of eastern Oregon. Through investigations in vertebrate and invertebrate paleontology, paleobotany and physical geology, an attempt is being made to construct as completely as possible the history of the development of animal and plant life and of geologic and climatic changes in this part of the northwest in the later eras of geologic time.
