Yes,
it’s really pink. All the time. No, Dr. Seuss didn’t fill it with pink
ink, although that was the first thing that came to mind. This is one of
many pink lakes, ponds, and lagoons in Australia, and there are
actually quite a few pink lakes found around the world. Many of them can
blame the color on an algae known as
Dunaliella salina, which uses a reddish pigment for photosynthesis. Or they may be infested with
Halobacteria,
which also gives a pink hue. Yet another way a lake can turn pink is
due to minerals in the surrounding rock that dissolve in the water, such
as salt. You can see
a roundup of pink lakes from all over at Scribol.
