Hillier Lake, western Australia: The pink and lovely Hiller Lake, is the
only vividly pink lake you will find in the world. The color is
permament and never changes, even when water is removed and placed in a
separate container. Its startling color remains a mystery and while
scientists have proven it’s not due to the presence of algae, unlike the
other salt lakes down under, they still can’t explain why it’s pink.
