Our project examines the cultural history of Paleo-Inuit occupation (4000 - 1000 years before present) along the coastlines of northern Foxe Basin, Nunavut. This region comprises the core area of Paleo-Inuit development, and most researchers argue that populations here were stable and continuous until the arrival of the Thule Inuit (ancestors of modern Inuit). It is also implied that the earliest Paleo-Inuit archaeological culture - the Pre-Dorset - transitioned smoothly into the Dorset, whom are called Tunnit or Tuniit by Inuit today. Our research will challenge this model of perceived stability and provide a more nuanced perspective of Paleo-Inuit prehistory and the Pre-Dorset to Dorset transition. Our field site, NjHa-1, is located on Kapuivik (Jens Munk Island), around 50 kilometres northeast of Igloolik Point. It is optimally positioned to examine these assumptions because it contains a relatively continuous sequence of occupation from Pre-Dorset to historic dwellings. This research will continue excavations that began in summer 2016 on the island, and specifically target areas from the transitional period (2800 - 2500 before present). The summer 2018 field crew will include 3 graduate and 2 undergraduate students from McGill University in Montreal, as well as a bear monitor from Igloolik. We have received full support from the Polar Continental Shelf Program and they will provide rental gear, one to two ATVs, and Twin Otter flights to and from the island.
