Abstract
AbstractRecent excavations in south-central British Columbia have revealed a 7,500 year sequence which indicates cultural relationships with the subarctic and the Canadian Prairie Provinces, but few similarities with Columbia River sites until after A.D. 1000. South-central British Columbia and the Columbia Plateau are considered to have participated in different cultural traditions until the damming of the Columbia River about A.D. 1250 allowed the upriver passage of salmon. The similarities noted between British Columbia and Columbia River sites in late prehistoric times may be attributable to the sudden increase in the resource potential of the Columbia River.
