7. Lake Hillier In Australia
Just off the south coast of Western Australia, Lake Hillier is the most famous of Australia’s weird “pink lakes.” It is situated on the largest of the Recherche Archipelago Islands, Middle Island. Separated from the Southern Ocean by a thin long shore, this lake is well-known for its bubble gum pink hue. Surrounded by eucalyptus trees and a firm rim of sand, the lake is 600 meters (over 656 yards) in length.
It is a saline lake and the only living thing in it are Dunaliella salina. These microorganisms cause the salt there to create a red-colored dye. This and the halophilic bacteria in the salt crust are currently believed to be the cause of the pink color. Nevertheless, there are things about the lake that still intrigue and surprise researchers.
