Tanfield Valley is an archaeological site located on Baffin Island in the Canadian territory of Nunavut. It is likely that the site was known to Pre-Columbian Norse explorers from Greenland and Iceland. It may be in the region of Helluland, spoken of in the Icelandic sagas (the Greenland Saga and the Saga of Erik the Red). 
The Helluland Archaeology Project is an ongoing research initiative at the Canadian Museum of Civilization.  Excavations led by Patricia Sutherland found 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.
