This is fascinating, but I agree with you that it's still a mystery. Hjalmer Holand wrote an excellent book on his research of the Stone. He thoroughly debunked the sloppy reporting that surrounded the stone's discovery. But what was the most important fact of the case that made me believe that the stone could well have been a forgery is something not mentioned in this article. Several friends of Olaf had studied runes before immigrating. Also, a not altogether reliable, but very well educated, minister was involved. So reports that this man possessed just a few weeks of formal education is deceptive. However, I find the geological findings very, very interesting. The jury is not in on this one yet!
