The hypersaline water does more than grow cockles; it shelters living history. In these salty shallows, cyanobacteria, microscopic organisms that have existed for billions of years, trap and bind sediment into rocky domes called stromatolites. They are among the oldest forms of l...

Recognizing that a place this rare cannot be taken for granted, conservation authorities established a marine reserve here, part of the wider protection that earned the entire Shark Bay region its UNESCO World Heritage status. The bight is named, like so much of this coast, for t...
