Ceramics From the Highwalker Site: a Study of Late Prehistoric Period Cultural Systematics on the Northwestern Plains

Abstract

The Highwalker site is a two component prehistoric encampment located in the Pine Parklands region of southeastern Montana. The Late Prehistoric period occupation represents a briefly used, special purpose site occupied by a Native American group primarily engaged in the final butchering of bison and the processing of its by-products. Two radiocarbon samples date the Late Prehistoric period occupation between A.D. 1000 and A.D. 1100. Ceramics recovered from this component shed some light on the debate concerning Pottery and Late Prehistoric period cultural systematics. The ceramics represent the earliest known representatives of a localized Powder River Basin pottery tradition which appears to be related to Extended Middle Missouri Tradition ceramics. These nomadic Powder River Basin ceramic-using groups maintained contact with the Middle Missouri village farmers and were influenced by their pottery technology. Later when the ethnographically known Crow moved into the area, the Powder River Basin hunting groups either were amalgamated into Crow society or were driven from the area.
