Bugas-Holding, WY
thin deposit sealed by low-energy overbank sediments Late Prehistoric, ~500 BP
well preserved site merited new methods pioneered detailed piece-plotting use of taphonomic interpretation
excellent preservation small remains ~2-5 cm thick bone fragments animal remains heavily butchered tiny flakes (≤4 mm)
EDM Technology rapid accurate mapping sub-centimeter precision
Recovery of Small Materials 1/8” screen 1/16” screen small flakes small bone fragments rocks gastropod remains charcoal
Multiple Hearths 8 hearths with associated debris & ash dumps ash indicates minimal movement of artifacts Rapid burial high potential for site structural analyses
few stone tools small tools, heavily re-worked dominance of small flakes winter unavailability of new stone
bone implements
Map of Site hearth features conjoined bone fragments show movement of meat units across site distinct activity areas
conjoined bones traces movements of individual bones shows patterns of processing of particular anatomical units
stone boiling hearths 4 hearths in same area bone debris indicates removal of fatty articular ends boiled to collect bone grease
Butchering map impact fractures on fragments map cutmarks on fragments allows statistical examination of butchering practices although almost no complete bones
Taphonomy same processes preserving archaeological site preserve natural bone accumulations shed elk antler natural bison death followed by archaeological occupation
Bison remains targeted individual animals, especially pregnant cows complete butchery seasonality from fetal bison bones=late winter early spring camp
mountain sheep remains catastrophic kill frozen caches of articulated units periodic recovery and input to camp
Sheep Trap archaeological evidence of sheep traps in Absaroka Mountains drive lines and trap drop kill results in catastrophic kill-all ages in population
Elk remains individuals infrequently brought to camp complete butchery
Dead Indian Site, WY deeply stratified deposits at least Archaic-Late Prehistoric deer bones dominate all archaeological levels
