The association of Paleo-Indian sites with high quality lithic outcrops seems to hold true for the Delmarva Peninsula. Almost all of the known Paleo-Indian tools and projectile points found on the peninsula are made from materials found at either of the two major lithic sources. Remote sensing was used to develop a map identifying swampy areas which would correspond with the Paleo-Indian sites. The biface technology, which produced the maximum number of tools for unit of stone, became the major mode of adaptation to the existing resource distribution, underscoring the fact that suitable stone was the most critical resource and provided the focal point for the wandering patterns. -- AATA
