- Comments
- JhVq-1, Gladstone: Component 1 consists of a thin scatter of artifacts, probably assignable to the Aishihik phase, within Neoglacial loess above the White River tephra. Component 2 is the main occupation at this site, representing the Taye Lake phase in the top of the Slims soil immediately below the tephra. Component 3 is represented by a sparse scatter of microblades and other tools at the base of the red zone of the Slims soil, and it is assigned to the Little Arm phase. When the dates were acquired, Morlan considered all of them too recent (see Wilmeth 1978: 2). In the light of more recent work in the region, only S-777 is now considered anomalous because it is more recent than the tephra that lies above it. The S-777 assay may have suffered from the method of pretreatment, insoluble collagen extraction, that often produced spuriously young results.
