The Dighton Rock

The Dighton Rock is a 40-ton boulder located on the shores of the Taunton River in Massachusetts and it is covered in puzzling petroglyphs. For nearly 300 years, people have speculated about its origin and meaning. Investigators have attempted to decode the odd glyphs since an English colonist first described the boulder in 1680, but they have had little success. In 1963, state officials removed the boulder and kept it for preservation. Most scholars think the stone carvings are of Native American origins. Some of the wilder theories have proposed that it was the work of the Portuguese, Chinese, or even the ancient Phoenicians.
