Cloughmore Stone, Kilbroney Forest Park, Rostrevor, Co Down, N Ireland (Explored)

The granite boulder, which has a calculated mass of 50 tonnes, is a glacial erratic, thought to have been transported from Scotland (from an island in Strathclyde bay) and deposited about 10,000 years ago by retreating ice during the last Ice Age. It sits on a relatively flat area of Silurian metasedimentary rock. Or, if you are a local it’s just referred to as the ‘The Big Stone’
