[1] The bluff slopes sharply (200 feet) [3] into the Pearl River floodplain. [2]
The Twelve Apostles were formed by erosion. The harsh and extreme weather conditions from the Southern Ocean gradually erode the soft limestone to form caves in the cliffs, which then become arches that eventually collapse, leaving rock stacks up to 50 m (160 ft) high. The stacks are susceptible to further erosion from waves.
