As I have mentioned in other writings, sooner or later some group of scientists will undertake to sample the mtDNA of certain native peoples of southeastern Canada, including the Cree of the Ungava Peninsula of Quebec, and the northeastern United States for Norse genetic markers.
Such a study is the only way to finally put to rest the 1000-year old mystery of what happened to the Greenland Norse settlers.
This effort should concentrate on a cross section of pure blooded members of the Cree, Ojibwa, and Iroquois Indian tribes. I submit that Norse genetic markers will be found in these Indians as they have been found in the male Inuit(Y-chromosome) of Greenland, although none have been found in female Inuit.

This work will no doubt continue and extend into other areas of the Canadian Arctic.
Given the tremendous distances involved, the high cost of travel in the Arctic, primitive conditions, and the shortness of the summer season, it seems plausible that DNA studies will prove to be cheaper than archaeological excavations.
