This refers to the Minnesota stone, not the Kensington one in case people are confused....it wasn’t well-written.
I remember seeing this on an interesting History Channel documentary about this, and they had some skepticism toward the Minnesota stone.
Correct! The Kensington Runestone wasn’t even recognized as having a carved text until it had been in use for some years in a building. Sounds like the hoaxer *really* wasn’t in much a hurry. ;’)
