Earlier this year, a caver was poring over satellite images of the Nullarbor Plain when he came across something unexpected: an enormous, mysterious scar etched into the barren landscape.

After the caver noticed a giant gash across a barren landscape, scientists discovered it was created by a ferocious tornado that no-one knew had occurred.

The accidental discovery of an 11-kilometre long ‘scar’ carved into dirt and rock in Australia’s remote outback has puzzled scientists since its abrupt emergence two years ago.
