I might also note the many sites along the Atlantic seaboard, they finally let the northernmost one, at the very north tip of Newfoundland, be excavated in the Sixties, but there are 30 or 40 others in Newfl. alone, also some 30 in Nova Scotia, some 300 in New England, and a dozen south of that.
Holand and others have found about 200 norse objects in Minnesota, (and a few in Wis, Mich, ND) pertain to the era of 1362 or the Viking era...and then there is that whole fort on the Missouri 25 miles below Pierre, SD, on the east bank, isn't that Norse? Certainly European and medieval.
