Tasmania has many sea cliffs made of dolerite, often in the form of columns. However the
Bicheno Blowhole is made of
granite. The ocean has beaten against the
granite for thousands of years, carving out a sea
cave from a joint on
the rock The waves in assaulting the
cave’s interior, located a weak area in the ceiling and ripped a hole in the
granite. Now,
water rushes into the
cave, splatters against the walls and erupts out the ceiling hole. For those standing at the side of the sea
cave, this provides a geyser effect.
With each surge of the ocean, the geyser bursts with changing force, and the
water takes on new shapes. Even when the sea is calm, it can blow with enormous force, so never turn your back on the
blowhole. When the ocean is angry, though, the most spectacular and dangerous eruptions occur.
