Eaglehawk Neck Tessellated Pavement - Eaglehawk Neck, Australia

Resembling a manmade pavement, Eaglehawk Neck is an isthmus which connects the Tasman Peninsula to Tasmania. The isthmus is covered in regular, rectangular-shaped saltwater pools. While they look human made, they are caused by a rare type of natural erosion. The phenomenon is extremely rare and found in only a few places in the world.
