The lake Hillier was discovered first in 1802
by Matthew Flinders, who was a navigator
and cartographer. He took the water samples from this lake and also mentioned
about its existence in one of his journals. The reason for the pink colour of
this lake water is still a doubtful topic, that the scientists do not declare
an exact reason for it, however, most scientists suspect that the lake consists
of the presence of microalgae of the Dunaliella Salina. This microalgae
produces carotenoids which is a colour pigment often found in carrots, so the
water appears in the pink colour. But another theory is that the presence of a
bacteria named as Halophilic in the salt crusts make a chemical reaction in
between the salt and the sodium bicarbonate as a result the water turns into
the colour of pink. The water in this lake is safe to swim.
