With its amazing events, nature never fails to astound us; among the most amazing geological beauties on Earth are pink lakes. These unusual natural events turn regular salt lakes into breathtaking pink-hued bodies of water, generating dreamlike settings that would seem to fit another planet. From Australia to Senegal, these nine amazing pink lakes highlight the amazing variety of geological processes on Earth as well as the amazing interaction between microscopic life, salt concentrations, and ambient circumstances producing these enchanted pink waters.
1. Lake Hillier, Australia
One of the most vivid pink lakes in the world, Lake Hillier is situated on Middle Island on Western Australia. With a rim of white salt crystals and a thick grove of eucalyptus trees around, this amazing natural beauty contrasts dramatically with its bubble-gum pink waters. It is roughly 600 meters long. Dunaliella salina microorganisms, which generates carotenoids including beta-carotene as part of their photosynthetic process, are mostly responsible for the unusual hue of the lake. Unlike many other pink lakes, Lake Hillier stays remarkably pink all year long independent of temperature fluctuations or weather. Nearly ten times saltier than the ocean, the great salinity of the water provides ideal circumstances for these halophilic (salt-loving) species to flourish and generate their unique pigment.
2. Las Coloradas, Mexico
Part of an industrial salt production complex, the pink lakes of Las Coloradas in Mexico’s Yucatan Peninsula unintentionally produced one of the most often photographed natural events in North America. Stretching across the shore, these large salt ponds produce a patchwork of pink and rose-colored waves that sharply contrasts with the blue sky overhead. Red halophilic bacteria, brine shrimp, and particular algae species that thrive in the hypersaline environment provide the strong pigment. These lakes have so high salt concentration that salt crystals often develop along their margins, forming natural walkways glittering in the sunlight. The conventional salt-harvesting techniques applied here trace back to the Mayan civilization, therefore giving this geological wonder a remarkable historical context.
