Runestone in Minnesota

While traveling into Minnesota from North Dakota there was a stop at Ashby for a week. Taking in the local sites, birdwatching and museum visiting, I came across this interesting artifact known as the Victor Setterlund Runestone at the Grant County Museum in Elbow Lake, MN.
The rest of the museum was in fact more interesting but this caught my eye as I always look for strange or unexplained artifacts, a physical piece of material more substantial than most legends.
Enclosed in a glass case with a note of explanation on the side of the case explained the following object of interest.

It is really a beautiful piece of work to look at and one could in some way hope to chat with Mr. Setterlund to fill in some blanks of the story.

Although there are several unexplained runestones that exist and can be visited, and more mentioned to exist while their location is kept somewhat of a secret allegedly to preserve them, this one came with an open explanation.

On a note on the side of the glass case this runestone is enclosed in reads:

The Victor Setterlund Runestone

caused considerable excitement when found in 1949. The runic inscription reads "1776 Four Maidens Set Camp On This Hill". A cast of this stone was sent to Dr. Holand, the Kensington Runestone Authority, who misinterpreted the date as being 1376, the same period as the Kensington Runestone which added to the confusion. Mr. Setterlund, who had little formal education, studied runic characters and by this self study was able to correctly inscribe this prank inscription. It is displayed, not only because of the exitement (sic) it caused at the time, but as evidence that such a runestone could be made by a Grant County farmer.

I appreciate the honesty of the museum and this little chunk of history. Later on in my travels I will visit a much larger runestone that is certainly much more historical and seemingly unexplained.
