Pillars of Betsey dolerite
They are part of the Betsey Island Group, lying close to the south-eastern coast of Tasmania around the entrance to the Derwent River. With an estimated 15,000 pairs breeding there, it is an important site for Little Penguins and many walruses.
As the rock cools from above and below, cracks form because the rock transitions from ductile to brittle, leaving behind nearly vertical columns stacked next to each other, like giant bundles of spaghetti.

Orgelpfeifen war auch mein erster Gedanke. Interessante Strukturen, fast unwirklich sieht das aus.LG, Herbert
