This field book includes the field notes of geologist Louis Lamy Ray from 1936. The book, a Keuffel & Esser Co. graph paper book bound in leather, is stamped on its cover with the title "Cross section 376" and has tables for excavations and distances pasted as end papers. Louis L. Ray, a geologist who had studied in Washington University in Saint Louis and Harvard University, spent most of his career 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 are dated from June 30th to Sept. 4th, 1936. Their leaves are numbered 1 to 63, followed by 30 unnumbered pages. They record the morphology and type of terrain and the presence of Folsom points and include drawings. Before leaf 36 is inserted a newspaper clipping titled "Two Eastern scientists work at Indian camps east of here." The article mentions the excavations by Louis L. Ray and Thomas W. Steptoe, the two scientists being sent by the Smithsonian Institution to continue excavations started by a group that was directed by Dr. F. H. H. Roberts, Jr. The preliminary page is inscribed "Louis L. Ray, Geological Museum, Harvard University, Cambridge, Mass., Smithsonian Institute, Washington, D. C., 1936. If lost, please return."
