Australian scientists have discovered a lake unaffected by climate change and man-made chemicals The Inquisitr reported.
In fact, the lake is in the same chemical state it was 7,500 years ago. Researchers chose to call it Blue Lake.
"It's like God's bathtub," said Dr. Cameron Barr, of the University of Adelaide. "It is beautiful. It is absolutely beautiful. It appears that Blue Lake has been an important climate 'refuge' for the freshwater biota of the region, and is in the same condition now as it was 7,500 years ago."
Researchers published a study in the journal Freshwater Biology that looked at the chemical quality of the lake, among other things, according to UPI.com.
Scientists at the University of Adelaide studied historical photos, along with, fossil pollen and algae in order to determine what the lake looked like hundreds or even thousands of years ago.
They discovered the lakes shape, size, and chemical makeup had not changed. The phenomenon had not been seen in any of the other lakes that the researchers looked at.
The area in Australia that the lake is in did go through one drastic climate change about 4,000 years ago. The climate became drier, but the lake was somehow unaffected.
Barr stated that with appropriate preservation, the lake could remain unchanged for thousands more years. He did not have an opinion as to how tourism could affect the lake, but did say that sunscreen could change it's chemical makeup.
"Because it's constantly being updated it doesn't suffer from the vagaries of the climate in so far as it doesn't evaporate and become more saline ... It doesn't fill up and become fresher. It just remains constant," Barr said. "This place seems to be quite unique in that it shows such an amount of stability. So in that sense it's a refuge for freshwater biota away from those variable environments. We would argue that it's likely to be a freshwater refuge for some time in the future if managed properly."
