The deeper story
Edinburgh’s volcanic high ground
Arthur’s Seat and the nearby crags are the remains of a volcano that erupted around 340 million years ago, later carved by glaciers. Holyrood Park also preserves traces of much earlier people, including Stone Age evidence and Bronze Age settlement. At Salisbury Crags, James Hutton’s observations helped shape his thinking about the vast age of the Earth.
