Lake MacDonnell | Pink Lake Tour in Port Lincoln, South Australia | Eyre Peninsula, Blue & Pink Lake 

Welcome to my channel Crush On Australia.
1. Lake MacDonnell is a salt lake on western Eyre Peninsula near the Nullarbor Plain. The closest town is Penong. It is the site of a former salt mine and the largest gypsum mine in Australia, on the largest gypsum deposit in the southern hemisphere
Why is Lake MacDonnell pink?
The Pink Lake is caused by salt loving algae called dunaliella salina and bacteria called halobacteria that secrete carotenoid red pigments, that turns the water bright pink.
