Tanfield Valley, also referred to as Nanook, is an archaeological site located on Imiligaarjuit (formerly |Cape Tanfield), 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.

[2][3] The Helluland Archaeology Project was a research initiative that was set up at the Canadian Museum of Civilization, now the Canadian Museum of History, to investigate the possibility of an extended Norse presence on Baffin Island with trading with the indigenous Dorset people.

[5] Excavations led by Sutherland at Tanfield Valley found possible evidence[6] of medieval Norse textiles, metallurgy and other items of European-related technologies.

Moreau Maxwell (1918–1998), professor and curator of Anthropology at Michigan State University, had previously researched the site in his study of the prehistory of Baffin island, the findings of which were summarized in his publication Prehistory of the Eastern Arctic (1985).
