In this episode of New England Legends, we head north of Boston to explore America’s Stonehenge, a 4,000-year-old mysterious calendar in Salem, New Hampshire, then head south to Dungeon Rock in Lynn Woods on Boston’s North Shore to investigate a tale of pirates, buried treasure, and Hiram Marble, a man who spent his life tunneling a cave through solid rock because spirits told him there was gold to be found. But did he find it? Is the gold still there today?
