There are also oral tradition legends about blond haired , blue eyed native Canadians. There is also the historical record...
When Lewis & Clark wintered in North Dakota, they were hosted by blond haired, blue-eyed Mandan "indians".
I suspect this particular remnant would be associated with Minnesota's Kensington Runestone, but they likely would've originated in Greenland or Newfoundland.
excerpt: Remaining in the Pacific Northwest, the question naturally arises as to whether representations of the "Sisuitl" might exist among the many petroglyphs in the region. Bearing in mind two things - firstly, the crocodilian snout plus the large eyes, and secondly, that an exact match with a Viking figurehead would be extremely difficult to emulate - its nevertheless seems that some examples of "Sea-Monster" petroglyphs do exist in this context, such as those found at Sproat Lake near Barkley Sound and Nanaimo. Oddly enough, in casting about for a suitable match, one of the most complex figureheads found was that used on the "Sigrid Storrada replica Viking Ship (lower right inset, Figure 7-1b below; Defunct link: http://www.sigrid-storrada.com/ ). This figurehead along with that of another working replica, the Danish Vikingship Helge Ask (lower left insert) are compared below with "Sea-monster" petroglyphs at Nanaimo on the east central coast of Vancouver Island, British Columbia:
