Last weekend, we took a plane and flew over the Twelve Apostles. They are spectucular rock stacks that rise up to 70 metres from the ocean. These amazing formations are remnants from constant erosion of the limestone cliffs of the mainland that began 10-20 million years ago. Stormy ocean waves and winds gradually eroded the cliffs creating these arches. They are still eroding and some 15 years ago, people had walked out to view them on connected land like the one in front. Suddenly, the rock gave way in the middle, stranding the people out on a stack. No one was injured, but the people had to be rescued via helicopters. So we viewed them from a safe distance - in the sky!
