Dighton Rock State Park is an 85-acre (34 ha) Massachusetts state park located in the town of Berkley, managed by the Massachusetts Department of Conservation and Recreation. The park is named after Dighton Rock, an 11-foot-high (3.4 m) glacial erratic that once sat on the banks of the Taunton River, covered with petroglyphs. It has since been moved to a small museum on the park grounds (pictured at right).
