A broad shelf of grey rock runs down to the sea at Pirates Bay, divided into neat rectangular blocks like the floor of some drowned cathedral. The Tessellated Pavement at Eaglehawk Neck is so regular, so deliberate-looking, that visitors have long struggled to believe nature made it without help. But no mason laid these tiles. The pattern is the work of stress, salt, and the sea, acting on stone laid down before the dinosaurs, and it produces one of the most photographed natural surfaces in all of Tasmania.

Tessellated Pavement: Cracks Older Than the Dinosaurs

Over the eons that followed, the Earth flexed and the rock was put under enormous stress. Rather than shattering randomly, it fractu...

The pan formation appears farther from the shore, where the rock dries out more fully between tides. Salt crystals grow in the centre of ...

Tessellated Pavement: A Form Found Around the World

Photo credit Gillian from Sydney, Australia, CC BY 2.0. Tessellated pavements are rarer than they sound, and geologists recognise several distinct ways they can form. Some are born of cooling lava that contracts into columns, some of drying mud that cracks and is later filled and turned to stone, and some, like this one, of solid bedr...

Tessellated Pavement: Best Seen at the Edges of the Day

Photo credit Felix Andrews (Floybix), CC BY-SA 3.0. Timing is everything here. At high tide the pavement vanishes beneath the swell, just another stretch of restless water. At low tide it emerges fully, the grid running out toward the breakers, often with shallow water still pooled in the pans to mirror the sky. Photographers favo...
