||The Arnold Research Cave, overlooking the Missouri River in southeast Callaway County, has been dry for thousands of years, making it the perfect potential location for evidence of prehistoric habitation. With these conditions, archaeological excavators in the 1950s, and later the 1980s, found remaining artifacts made of perishable materials, such as netting, twined bags and clothing, including—perhaps of the greatest popular interest—the world’s oldest open-toed sandal. In "Shoes Older than the Pyramids," Dr. Candace Sall, Associate Curator of the University of Missouri’s Museum of Anthropology, will provide details on many of the artifacts found in the cave, including 35 individual shoes made of rattlesnake master, a plant native to the Show-Me State. The items unearthed at the site range in age from 800 to 9,000 years, with the earliest shoes dating back 8,000 years, making them some of the oldest articles of clothing ever found in North America. Join us as Dr. Sall discusses these artifacts, providing a fascinating glimpse into the lives of Missouri’s prehistoric peoples.
