Current research at western Oklahoma's Certain site (34BK46) has subst
antially increased our knowledge of Late Archaic bison hunting in the
Southern Plains. Comparison with several other kill sites in the Texas
Panhandle shows a broad, regional pattern. Small to moderate numbers
of bison were frapped in arroyos, killed, and butchered. Butchering pa
tterns and carcass utilization vary in detail, but generally show less
than full use of what was available. Seasonality data are tentative,
but seem to show some variability as to timing of the kilts, with a po
ssible preference for late fall/early winter.
