Cliff Dwellers of the Ozarks will be the focus of the Feb. 4 installment in the Historic Tuesday Talk series in the Rosemary Berkel and Harry L. Crisp II Museum at Southeast Missouri State Universitys River Campus.Local historian Dr. R. Bruce McMillan will give the presentation at 7 p.m., which is free and open to the public.McMillan will explore the White River basin in southwest Missouri and northwest Arkansas a region noted for bluff shelters that contain remarkable preservation environments -- one that preserves what are otherwise perishable artifacts. These dry shelters produce hafted tools and weapons, baskets, woven fabrics, clothing and footwear, and perishable food items along with ceramics and lithic artifacts.McMillan will also discuss how Mark Harrington, an archaeologist trained at Columbia University in New York, first described what he called the Ozark Bluff Dweller culture in 1924, following two years of explorations in these bluff overhangs. Harringtons collections ended up at the Museum of the American Indian in New York. A decade later, the University of Arkansas Museum under the direction of Samuel Dellinger, excavated 80 additional bluff shelters amassing a large collection of perishable artifacts that are today curated by the Arkansas Archaeological Survey. In 1957, as part of the work in the Table Rock Reservoir area, Carl H. Chapman of the University of Missouri excavated several dry shelters in Barry County, Missouri. McMillan will review the history of this work along with an explanation of how the concept of an Ozark Bluff Dweller culture has outlived its usefulness.McMillan is a research associate with the University of Missouris Department of Anthropology; director emeritus and research associate at the Illinois State Museum; and adjunct professional scientist with the Illinois National History Survey at the University of Illinois at Urbana-Champaign. He holds a doctoral degree in anthropology from the University of Colorado-Boulder; a Master of Arts in anthropology from the University of Missouri-Columbia; and a Bachelor of Science in education from Missouri State University in Springfield.
