The Davidson Site (AhHk-54) in Southwestern Ontario continues to yield a wealth of information about the Late Archaic period in the Great Lakes Region. Excavations have shown the site to contain the well-preserved remains of pit-houses and other structures, as well as vast numbers of pits of varying description, including storage and refuse features. This research focuses on the interpretation of two enigmatic clusters of overlapping pit-features, both of which have been tentatively dated to the Small Point Late Archaic of ca. 3,200-2,600 BP. Relatively shallow, basin-shaped proflies characterize the pits that form these clusters. Their contents are dominated by concentrations of fire-cracked rock (FCR) of material types that are not local to the immediate site environs. This presentation discusses the preliminary results of attempts to interpret these FCR through basic analyses of their spatial distribution, material sourcing and selectivity, attempts at refitting FCR, and their replication through experimentation with ethnographically recorded hot-rock cooking technology. Similar clusters of pit-features with high numbers of associated FCR have been recorded as a characteristic of Late Archaic sites in the Great Lakes region, and have been described variously as earth ovens, hearths, and roasting pits, as well as general refuse and storage features. While these descriptions can be useful in aiding site interpretations, their classifications often go untested, and the conspicuously present FCR remain virtually unrecognized as cultural material. The analyses presented here may serve to test the potential analytical value of fire-cracked rock in the Late Archaic in the Great Lakes Region.
