Scientists have discovered a lake in Australia, which has never been affected by climatic changes or any other man-made influences. Its water is in the same chemical state as 7,500 years ago. It is like God's Bathtub, named now Blue Lake. It is one of the largest on North Stradbroke Island of the south Queensland coast, is so pure that you can see even more than 30 feet below the surface to its bottom. It is the only such lake of its kind in Australia. Several other nearby lakes have dried up during the last 40 years, but its water has remained unchanged, because its waters drain into a nearby swamp and are replaced by an aquifer every 35 days or so.
