Bison Procurement in the Far West: A 2,100-Year-Old Kill Site on the Columbia Plateau

Abstract

Bison bones are found in Columbia Plateau archaeological sites from throughout the Holocene, yet no information on people's tactics for procuring them has yet been reported. The discovery of the Tsulim Site, a 2,100-year-old bison kill near the Columbia River in central Washington, has provided the opportunity to investigate those tactics. Despite the deteriorated state of the evidence, analysis of stone artifacts, faunal remains, and site geology revealed that at least eight animals were killed in the apex of a parabolic dune during the early to mid-winter by hunters using both atlatl and bow. Local topography and meteorology make it most likely that the herd was encountered in a low paleochannel, driven northward between the limbs of the dune, up the steep channel wall, and into the kill area, a sort of inverted buffalo jump. Results not only illuminate the large-game hunting practices of the Plateau peoples, but also point out how much can be learned from disturbed, low-density scatters of debris that are often dismissed as insignificant.
