"[3] Archaeologist Lyle Tompsen in a 2007 Masters Thesis for the University of Leicester (published in ESOP 29 2011:5-43) examined the runestone and noted: "Barring any new evidence, the stone is best considered a modern creation.
That’s another thing that doesn’t really fit the pattern.” He also noted that "There are no Vikings or earlier inscriptions on Iceland or Greenland, so it’s a big jump from Sweden to Heavener.
