Open-air sites, especially those dated to the late Pleistocene and early Holocene periods, are notoriously difficult to find. Site formation and taphonomic processes challenge preservation, making identifying discrete activity areas and even site boundaries particularly challenging. In Diversity in Open-Air Site Structure across the Pleistocene/Holocene Boundary , Kristen A. Carlson and Leland C. Bement gather a group of investigators who meet these challenges. In the nine chapters, the authors present case studies analyzing a variety of open-air sites located in Europe and North America to demonstrate that with careful excavation and clever spatial analyses, open-air sites can offer valuable new information about past lifeways
