Red chert from the Munsungun Lake Formation Northern Maine, is among the most readily identifiable lithic raw materials in the western Maritime Peninsula. The identification of Munsungun chert has provided important insights into how ancient Indigenous populations interacted with their environments, landscapes, and each other, especially during the terminal Pleistocene. Despite the demonstrated importance of this distinctive toolstone, a quarry local for this material has only recently been identified by archaeologists. Further, although the presence of red Munsungun chert during the fluted-point-period has received considerable attention, its absence in the Early Holocene toolstone assemblages is less extensively explored. Here I present the results of recent survey and excavations at the only currently known red chert quarry within the Munsungun Lake Formation. I will then discuss what the absence of red Munsugnun chert in Early Holocene archaeological sites may indicate about social change in the far Northeast at the end of the Ice Age.
