This field book includes the field notes of geologist Louis Lamy Ray from 1937. The book, a Keuffel & Esser Co. graph paper book, is stamped on its cover with the title "Cross section 375"; 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 written on mostly unnumbered pages, with the exception of the first five ones. They are dated from June 27 to September 9, 1937 and describe both findings and theoretical thoughts on areas of Colorado. The preliminary page is inscribed "Louis L. Ray, Harvard University, Dept. of Geology, Cambridge, Mass. or Smithsonian Institute, Washington, D. C. If lost, please return -- June 1937."
