Sutherland is an expert in Canadian indigenous archaeology. In 1977, surveying what was to become
Quttinirpaaq National Park, on
Ellesmere Island, for
Parks Canada, she found a piece of bronze that turned out to be half of a Norse silver weighing balance. This and evidence of metalworking–bronze and smelted iron, in addition to
whetstones used for sharpening metal implements–and tally sticks like those used by the Norse, found at four sites where Dorset people had camped as much as 1,000 miles (1,600 km) apart between northern Baffin Island and northern Labrador, suggested both long-term trading contact between the Norse and the Dorset, and a long-term presence of Norsemen in the region. She presented her view at an exhibition titled
Full Circle: First Contact, Vikings and Skraelings in Newfoundland and Labrador, which opened at the
Provincial Museum of Newfoundland and Labrador in summer 2000, and at a meeting of the Council for Northeast Historical Archaeology in St. John's in October 2012. The
radiocarbon dates of items at the Nanook site include some predating the Norse by several hundred years.

Lascaux caves in
France, "We now have at least two pieces of evidence that this important principle of twisting for strength dates to the
Palaeolithic. The international
Helluland Project, organised by Sutherland, was to have published a book on her findings; this has been suspended as a result of her loss of access to her materials. ==Personal==
