Richard LeRoy Hay was a geologist, known for his contributions to sedimentary petrography and archaeological geology. This collection contains field notebooks, maps, photographs, data, and documentation of geological specimens he collected, primarily in Africa, but also in the United States, Europe, and Asia. He was known for his work with Mary Leakey, in which he provided the geological framework for Olduvai Gorge and Laetoli in Tanzania.

Scope and Contents
Scope and Contents
This collection comprises the professional papers of Richard LeRoy Hay. Among his papers are his correspondence with Mary D. and Louis S. B. Leakey and his research at Olduvai Gorge and Laetoli, consisting of his field notebooks, maps, photographs, data, and documentation of geological specimens he collected. Also in the collection is his research at other sites in East Africa, including Kerimasi and Oldoinyo Lengai in Tanzania and Rusinga Island in Kenya. To a lesser extent (although still a significant amount) in the collection is the documentation of Hay's research in the United States. Present are field notebooks and photographs from his research in Amargosa, Nevada which served as a geologic analog for Olduvai. Also in the collection are field notebooks spanning from 1958 to 2004 containing his notes on his research in Oregon, Hawaii, Wyoming, California, New Mexico, Colorado, Arizona, Wisconsin, and other regions in the country. Mixed in are notes from his research in other countries including Pakistan, Scotland, and France. The collection includes his field notebooks from his service in the U.S. Army Corps of Engineers, during which he spent some time in Japan. There are no notes from his work as a geologist for the U.S. Geological Survey.

Biographical Note
Biographical Note
Richard LeRoy Hay was a geologist, known for his contributions to sedimentary petrography and archaeological geology. He worked closely with Mary Leakey for more than thirty years and provided the geological framework for Olduvai Gorge and Laetoli in Tanzania.
Hay was born on April 29, 1926 in Goshen, Indiana. He attended Ursinus College briefly (1944-45) before transferring to Northwestern University, where he received his B.S. (1946) and M.S. (1948) in geology. In 1952, he earned his Ph.D. in geology from Princeton University and served in the U.S. Army Corps of Engineers (1952-54).
After leaving the army, Hay worked as a geologist for the U.S. Geological Survey (1954-1955) and in 1955 began his academic career at Louisiana State University, Baton Rouge (1955-57). In 1957 he accepted a position at University of California, Berkeley and remained there until his retirement in 1983. From 1983 to 1997, Hay was Ralph E. Grim Professor of Geology at University of Illinois, Urbana Champaign, and later had an appointment as adjunct professor at the University of Arizona, Tucson (1998-2006).
Hay made his first trip to Olduvai Gorge in 1962 and continued to research and publish numerous articles on Olduvai for the next four decades. His most significant publication was his monograph,
Geology of the Olduvai Gorge
(1976), in which he provided a detailed study of the geologic history of Olduvai, placing hominid remains and other archaeological findings at the site in a paleogeographic context. Also significant was his geological analysis of tuff at Laetoli bearing early hominid footprints; he coauthored with Mary Leakey "Pliocene Footprints in the Laetolil Beds at Laetoli, Northern Tanzania" (1979) and "The Fossil Footprints of Laetoli" (1982).
In addition to Olduvai Gorge and Laetoli, Hay conducted geological fieldwork at Oldoinyo Lengai, Ngorongoro caldera, and Kerimasi volcano in Tanzania, as well as Rusinga Island, Lake Magadi, Amboseli, and Mount Suswa in Kenya. He also worked at several sites in the United States, including the John Day region of Oregon, the Green River formation in Wyoming, Amargosa Desert in Nevada, and Searles Lake in California. Additionally, he worked in west-central Wisconsin where he discovered the replacement of uppermost Precambrian and Cambrian-Ordovician rocks by low-temperature potassium-feldspar.
During his lifetime, Hay received many honors for his accomplishments in geology. He was a Fellow of the Geological Society of America, American Association for the Advancement of Science, and California Academy of Sciences. He was awarded the Geological Society of America's Kirk Bryan Award in 1978 and the Rip Rapp Archeological Geology Award in 2000. In 2001, he received the Leakey Foundation's Leakey Prize, awarded for intellectual achievement in the field of human evolution. Posthumously, a memorial was held for Hay at the GSA annual meeting in 2007.
Hay died at the age of 79 on February 10, 2006.

Administration
Processing Information
The papers of Richard L. Hay were received partially organized. Most of the collection was packed and sent from Hay's home in Tucson after his death. A small portion of Hay's Olduvai photos, reprints of his publications, and X-ray diffraction data were sent to the archives later by his colleague Marie Jackson. The processing archivist kept existing groupings and arrangement and organized the collection into eight series. Original folder titles were retained with titles assigned by the archivist placed within square brackets. Oversized materials were separated and replaced with notes indicating original and new locations.
