Description

Tasmania is made mostly of dolerite, a rock only found in Australia, but the blowhole is made of granite. For thousands of years, the ocean has battered the granite to carve out a sea cave underneath the coast. The water, battering the inside of the cave with increasing force, found a weak spot in the ceiling to blow a hole through the granite. Now water rushes into the cave, hits the walls, swells with increasing pressure and it all erupts out of the hole in the ceiling. This creates a geyser effect for those standing on top of the sea cave. No camping or overnight parking.
