"A mysterious, small aqua-blue pool of dense fluid has been discovered at the bottom of Crater Lake.
"'It is bizarre, it is remarkable,' said Jack Dymond, who with Robert Collier heads the three-year Crater Lake exploration project. 'I have never seen anything like it,' he said.
"The Oregon State University oceanographer said the pool, about 6 feet in depth, is approximately 3 feet wide by 8 feet long. It is near the lush white and orange bacteria mats found last summer."
The murky pool of fluid was discovered during a dive in a research submarine. The temperature of the pool was about 4.5°C (40.1°F) which made it 1°C warmer than the surrounding lake water.

Comment. Some lakes in northern climes still retain ancient seawater in their bottoms. Also, we have the well-publicized African lakes that suddenly overturn, producing clouds of poisonous gases. See our catalog: Anomalies in Geology. Ordering information here.
