A Geological Wonder in Tasmania: Cape Hauy

Cape Hauy, located on the southeastern edge of Tasmania’s Tasman Peninsula, is one of Australia’s most striking geological formations. Towering dolerite cliffs plunge into the Tasman Sea, remnants of a Jurassic magma intrusion that solidified into near-perfect columns and was later sculpted by erosion and rising seas. This natural fortress of rock tells a story of Gondwana’s breakup, tectonic uplift, and marine weathering—and offers a stunning glimpse into the geological forces that have shaped Tasmania over hundreds of millions of years.
