THE IDENTIFICATION AND PREHISTORIC SELECTION CRITERIA OF FIRE-CRACKED ROCK: AN EXAMPLE FROM DUST CAVE, ALABAMA

VIEWS: 38 PAGES: 17

This paper reports on two experimental studies designed to assess how Tuscumbia limestone from northwestern Alabama responds to heating. Experimentally derived fire-cracked rock was examined petrographically in order to develop physical correlates for thermal alteration. The experimental samples were then compared to archaeological samples taken from the Late Paleoindian through Middle Archaic site of Dust Cave, Alabama, to determine whether or not the limestone found there deserves a designation as fire-cracked rock. Results suggest that Dust Cave's occupants made use of locally available Tuscumbia limestone as part of their cooking and processing technologies rather than transporting more distant Tennessee River cobbles to the site. Results further suggest that the cave's occupants preferentially selected massively bedded varieties of Tuscumbia limestone over more thinly bedded varieties due to its higher tolerance for thermal stress and overall greater resistance to degradation during use.
