Tanfield Valley

Tanfield Valley, also referred to as Nanook, is an archaeological site located on Imiligaarjuit, along the southernmost part of the Meta Incognita Peninsula of Baffin Island in the Canadian territory of Nunavut. It is possible that during the Pre-Columbian era the site was known to Norse explorers from Greenland and Iceland. It may be in the region of Helluland, spoken of in the Icelandic Vinland sagas.

Archaeological investigations

Moreau Maxwell, professor and curator of Anthropology at Michigan State University, researched the site in his study of Baffin Island's prehistory, the findings of which were summarized in his publication Prehistory of the Eastern Arctic.
The Helluland Archaeology Project was a research initiative at the Canadian Museum of Civilization to investigate the possibility of an extended Norse presence on Baffin Island, including possible trade with the indigenous Dorset people. The project went on hiatus following Patricia Sutherland's ouster from the museum in 2012. While the project was active, excavations led by Sutherland at Tanfield Valley found possible evidence of medieval Norse textiles, metallurgy and other items of European-related technologies. Wooden artifacts from Dorset sites include specimens which bear a close resemblance to Norse artifacts from Greenland. Pelts from Eurasian rats were also discovered.
However, the eight sod buildings and artifacts found in the 1960s at L'Anse aux Meadows, located on the northern tip of Newfoundland, remain the only confirmed Norse site in North America outside of those found in Greenland.
