- NcVi-3, Dog Creek: The site consists of a series of surficial and buried cultural deposits on several knolls. Recovered lithic material is representative of various cultural complexes spanning a lengthy period, possibly late Pleistocene to mid- or recent Holocene. Cultural affiliation of the most prominent assemblage, characterized by burin and bifacial technology, is uncertain. A detailed geoarchaeological analysis revealed that the artifacts were buried by solifluction and disturbed by frost heave and cryoturbation. Solifluction took place about 5200-2000 years ago when the site was covered by spruce forest. Thereafter, the spruce treeline began to move southward toward its present position.
