点评:A beautiful site not to miss .. waking here and explore to other rock like Razor back, broken head nearby. It was formed after millions of years of erosion from the Southern Ocean.
About 20 million years ago, this entire area was a deep ocean. Sand from the rivers, fish and plant matter and other debris compacted at the bottom of the ocean and formed the Sandstone and Limestone coastline that is there today.
Originally, the erosion created an arch way before the cave. Eventually, the arch collapsed, now huge bits of Limestone and Sandstone sit just outside the cave at around 15 metres below the water surface. The water pushes over these huge chunks of stone and form waves that crash into the cave, contributing to the harrowing thunder that’s created a few times per minute on a wild day.

大约2000万年前,这整个地区是一片深海。来自河流的沙子、鱼类和植物物质以及其他碎片在海底压实,形成了今天的砂岩和石灰岩海岸线。
最初,侵蚀在洞穴前形成了一条拱道。最终,拱门倒塌,现在巨大的石灰岩和砂岩碎片位于水面以下约 15 米的洞穴外。水推过这些巨大的石头,形成波浪冲击洞穴,在狂野的日子里每分钟会发出几次令人痛苦的雷声。
