The stone that was at it's center is about the size of the Kensington rune stone. The texture of the rock looked the same as the Kensington stone, but the color was different. The boulder on the east coast was white. The Kensington rune stone is brown. Down the coast a few miles I saw on the map a pond called Norse pond.
Story is the pond has a hard bottom.
On the island just off the coast just a half mile from the magnetic sand was another mooring stone hole. It was no place to moor a boat but on the cliff overhead was a perfect place for a ship burial. There was a dead tree, old enough to have been first planted in the time of the Vikings, that seemed to mark a spot. The stone with the mooring hole may have slid down from that spot. What I found at the west coast at the 45th parallel.
