Dighton Rock


The Dighton Rock is a 40-ton boulder, 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."), carved designs of ancient and uncertain origin, and the controversy about their creators. In 1963, during construction of a coffer dam, state officials removed the rock from the river for preservation. It was installed in a museum in a nearby park, Dighton Rock State Park. In 1980 it was listed on the National Register of Historic Places (NRHP).AppearanceThe boulder has the form of a slanted, six-sided block, approximately 5 feet high, 9.5 feet wide, and 11 feet long. It is gray-brown crystalline sandstone of medium to coarse texture. The surface with the inscriptions has a trapezoidal face and is inclined 70 degrees to the northwest. It was found facing the water of the bay.HistoryIn 1680, the English colonist Rev. John Danforth made a drawing of the petroglyphs, which has been preserved in the British Museum. His drawing conflicts with the reports of others and the current markings on the rock. In 1690 Rev. Cotton Mather described the rock in his book, The Wonderful Works of God Commemorated: “Among the other Curiosities of New-England, one is that of a mighty Rock, on a perpendicular side whereof by a River, which at High Tide covers part of it, there are very deeply Engraved, no man alive knows How or When about half a score Lines, near Ten Foot Long, and a foot and half broad, filled with strange Characters: which would suggest as odd Thoughts about them that were here before us, as there are odd Shapes in that Elaborate Monument.…”
