Within the Cape Espenberg sites, layers of carbonized and cemented remains are found associated with Birnirk and Thule semi-subterranean houses (11th-18th century AD). These burned areas raise a number of questions about re related outside activities, the use of multiple fuels, and the long-term processes that led to their formation. In this wood-poor arctic environment, ethnographic observations report that driftwood can be used as a fuel, often coupled with animal resources to meet re energy needs. In this paper, we present combustion areas excavated from the Rising Whale site at Cape Espenberg. We analyzed each hearth feature by sorting and identifying wood and animal fuels. We discuss the representation of rewood taxa with a statistical analysis of their frequency and fragmentation.
