1. Pink Lake

Although the source of the pink colour has not been definitively proven in the case of Lake Hillier, the pink colour of other salt lakes (e.g. Pink Lake) in the region arises from a dye created by the organisms Dunaliella salina and Halobacteria.

2. As noted in some of the FB comments, it's not exactly a mystery.

3. Two different lakes

And, as yet, no definitive proof of the cause, as pointed out by PADemD above. http://en.wikipedia.org/wiki/Lake_Hillier

4. It's not unheard of for a lake to be pink.

Lake Hillier matches the composition and type of other pink lakes that are known.

But you're right, no one has yet done a specific analysis of what generates Hillier's pink hue, therefore unlike all the other pink lakes that have been studied, this one could be due to magic I suppose.

6. I didn't say the color of this lake "could be due to magic"

That's a ridiculous assertion.

Pink Lake (the one you said gives an explanation):

The lake is not always pink in colour but the distinctive colour of the water changes as a result of green alga Dunaliella salina, halobacterium Halobacteria cutirubrum, and/or high concentration of brine prawn. Once the lake water reaches a salinity level greater than that of sea water, the temperature is high enough and adequate light conditions are provided; the alga begins to accumulate the red pigment beta carotene. The pink halobacteria grow in the salt crust at the bottom of the lake and the colour of the lake is a result of the balance between, D. salina and H. cutirubrum.

Lake Hillier:



Nature (and life, for that matter) is still full of mysteries, that doesn't mean it's full of magic.

5. It looks like it is the source for Pepto-Bismol

If it is not Pepto-Bismol perhaps it is a lake of Klingon Blood.

7. Hadn't thought about that...

but I'm sure you're right. The only explanation that makes sense.
