Tanfield Valley, also referred to as Nanook, is an archaeological site located on the southernmost projection of Baffin Island in the Canadian territory of Nunavut. It is possible that the site was known to Pre-ColumbianNorse explorers from Greenland and Iceland. It may be in the region of Helluland, spoken of in the Icelandic sagas. The Helluland Archaeology Project is 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. It is now on hiatus following Patricia Sutherland's ouster from the museum in 2012. 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 have also been discovered. In 2018, Michele Hayeur Smith of Brown University, who specializes in the study of ancient textiles, wrote that she does not think the ancient Arctic people, the Dorset and Thule, needed to be taught how to spin yarn, remarking "It's a pretty intuitive thing to do." In 1992, Elizabeth Wayland Barber wrote that a piece of three-ply yarn that dates to the Paleolithic era, that ended about 10,000 BP, was found at the Lascaux caves in France. This yarn consisted of three s-twist strands that were z-plied, much like the way yarn is made now. The eight sod buildings and artifacts found in the 1960s at L'Anse aux Meadows, located on the northern tip of Newfoundland, remains the only confirmed Norse site in North America outside of those found in Greenland. Moreau Maxwell, 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.
