AVM Runestone
The AVM Runestone, also known as the Berg-AVM Runestone, is a hoax created in 1985 by students carving runes into a boulder near Kensington, Minnesota, not far from where the Kensington Runestone was found in 1898. In 2001, a carving expert and her geologist father found the AVM Runestone, told the press that it was proof of early Viking or Norse settlement in Minnesota, and began an investigation to prove its authenticity.
