This field book includes the field notes of geologist Louis Lamy Ray from 1939. The book, a Keuffel & Esser Co. graph paper book, is stamped on its cover with the title "Cross section 375 A"; it has tables for excavations and distances pasted as end papers. Louis L. Ray, who had studied in Washington University in Saint Louis and Harvard University, spent most of his career 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 ( a Paleo-Indian culture) artifacts at the Smithsonian Institution Lindenmeier site in Northern Colorado. The notes, which include drawings, are dated from June 27 to August 27, 1939, relate to geomorphology research that was conducted on western American geological sites (such as Scully Mountain, Agua Fria). The preliminary page is inscribed "Louis L. Ray, Dept. of Geology, Harvard University, Cambridge, Mass. 1939. If lost, please return to the above."
