Highly interesting analysis and documentation of three Monongahela Woodland American Indian archaeological sites excavated in Somerset County, Pennsylvania in 1939. Photographs, illustrations, and maps (many large fold-out maps) provide great detail of the excavation discoveries, and provide insight into the native Monongahela Woodland culture. Overall in excellent condition. Blue boards with gilt writing and decorations; 79 pages. The boards and binding are solid and tight, with little shelf-wear. The pages are crisp and clean save for Davenport Museum stamp on the top of the first blank page.
