Louis L. Ray (1909-1975), a geologist, was educated at Washington University (A.B., 1930 and M.S., 1932) and Harvard University (M.A., 1937 and Ph.D., 1938). Most of his professional career was spent as a Geologist with the United States Geological Survey. During 1936 and 1937, Ray participated in a Bureau of American Ethnology (BAE) excavation of Folsom Man artifacts at the Lindenmeier site in Northern Colorado. This collection includes Ray's field notes taken during his work with the BAE excavation, 1936-1937. The field notes document Ray's studies to determine the geological antiquity of the Lindenmeier site. Also included are field notes taken by Ray during research in Missouri, 1932, and Colorado and New Mexico, 1938-1939, and notes from research on his Master's thesis, 1930.
