Combining chert provenance and least-cost pathway analyses to reconstruct Pre-Dorset and Dorset mobility on southern Baffin Island

We combine chert provenance and least cost path analyses to investigate Palaeo-Eskimo mobility on southern Baffin Island, in the eastern Canadian Arctic. ICP-AES trace element analysis links chert artifacts from coastal and inland sites to quarries in the interior of the study area. Using a multi-criteria cost surface, we model least cost paths between quarry and occupation sites linked by the results of provenance analysis. These pathways will be used to structure a future program of pedestrian survey in the area between the coast and interior of southern Baffin Island.
