Spirit Pond runestones

The Spirit Pond runestones are three stones with allegedly runic inscriptions, found at Spirit Pond in Phippsburg, Maine in 1971 by a Walter J. Elliott, Jr., a carpenter born in Bath, Maine. The stones, currently housed at the Maine State Museum, are widely dismissed as a hoax or a fraud. If authentic, they would be evidence of pre-Columbian trans-oceanic contact and Norse colonization of the Americas.
Interpretation and authenticity.
Unlike the prehistoric monumental runestones raised in Scandinavia, the Maine stones are small handheld objects similar to the authentic Kingittorsuaq Runestone found in Greenland in 1824.
Of the three stones, one contains a total of 15 lines of 'text' on two sides. The "map stone" contains a map with some inscriptions. Paul H. Chapman proposes that the map depicts the landscape visible from the high White Mountain, the highest point in the vicinity of Spirit Pond, or the northern tip of Newfoundland.
The inscriptions contain several instances of the use of pentadic numerals in Arabic numerals placement. The first to study the stones scientifically was Harvard University professor Einar Haugen. In 1974, after transcribing, he found the individual runes used to be inconsistent with 11th century Old Norse, and that the text contains only "a few Norse words in a sea of gibberish". He also noted peculiarities relating the inscriptions directly to the Kensington Runestone inscription. Thus, he concluded that the inscriptions were most likely created after 1932.
Amateur researchers have been more sympathetic to a medieval origin of the stones. Suzanne Carlson of NEARA, a group of enthusiasts who believe there was a widespread Viking presence in North America, suggests a mid 14th century date for the inscriptions, although it is unclear how Carlson arrived at this date. Similarly, amateur rune-enthusiast Richard Nielsen claims a precise date of 1401.
