Wilson Butte Cave

Site of long occupation on the Snake River Plain in Idaho, starting c 14,500 bp - possibly one of the oldest occupations in North America. It is located on what is thought to be one of the major migration routes to the interior. Another date of 12,500 BC from an overlying stratum indicates the presence of man south of the ice at the height of the Wisconsin glaciation. Six layers covering a period of 10,000 years have been defined, five of which are middle-late Holocene. There are few artifacts, but tool assemblages indicate a hunting and gathering way of life prior to the Clovis specialization. the artifacts are biface, retouched blade, and flake.

A site of long occupation on the Snake River plain in Idaho USA. It is located on what is postulated as one of the major routes to the interior for migrating Paleo-Indian groups. A radiocarbon date of 14,450 be is regarded as unreliable, but a less controversial date of 12,500 be from an overlying stratum indicates the presence of man south of the ice at the height of the Wisconsin glaciation. Overall, a total of six accretional layers covering a period of 10,000 years have been defined at this site. Although artefacts are few, tool assemblages indicate a generalized hunting and gathering way of life prior to the Clovis specialization.
