King's Cave is the largest of a series of seafront caves north of Blackwaterfoot on the Isle of Arran in Scotland. The caves were formed around 10,000 to 6,000 years ago during an ice age when the weight of an advancing glacier forced the land downward, so the sea was higher relative to the location of the cave, with high tide around 4 metres (13 ft) up from its present level. When the ice melted, the land rose due to the isostatic rebound effect, thus forming a raised shoreline or raised beach with relict sea-cliffs. The hillside above the cliffs has a shallow slope resulting from a much earlier raised beach, nominally 30 metres (98 ft) above present high tide.
