A Change of Hearth: Stages of Production in Hot-Rock Technology at a Late Woodland Rockshelter (2018)
DOCUMENT Citation Only Luke Stroth. Rebekah Truhan. Jacob Foubert.

This paper applies the chaîne opératoire analytical framework to hearth maintenance behavior. There are distinct phases of production involved in creating and maintaining a hearth, as new hearthstones are introduced, exhausted, and discarded. These stages may be identified through spatial distribution of new and exhausted hearthstones. The authors argue that these stages may also be identified geochemically. We use pXRF to compare a series of experimental burnings to those from a hearth feature...
