Dighton Rock

Disputed: a Norse origin for this site has been claimed but is not accepted by mainstream archaeology. Listed for reference only. The Dighton Rock is a 40-ton boulder composed of sandstone, originally located in the riverbed of the Taunton River at Berkley, Massachusetts, formerly part of the town of Dighton. The rock is noted for its petroglyphs, "primarily lines, geometric shapes, and schematic drawings of people, along with writing, both verified and not". The carved designs are of ancient and uncertain origin, and there is controversy as to who created them. State officials removed the rock from the river for preservation in 1963, during construction of a coffer dam. It was installed in a museum in the nearby Dighton Rock State Park. In 1971, it was listed on the National Register of Historic Places (NRHP). Source: Wikipedia (CC BY-SA 4.0).
