The natural world. Looking pretty for 3.5b years.

God's Bathtub

Blue Lake in Australia has remained unchanged for 7500 years

Author: Hugh Bollinger/Thursday, June 6, 2013/Categories: natural history, environment

Researchers in Australia have discovered some remarkable facts about Blue Lake, a freshwater lake on North Stradbroke Island, off the Queensland coast.

Field researchers from the University of Adelaide sampled the island's water quality, discharge, reviewed photographs taken over the past century, gathered fossil pollen and algae samples, to develop a timeline of the lake's history. The depth, shoreline, and water chemistry of the crystal clear, blue water has remained constant for over 7,500 years.

The natural lake on the large sand island is more than 30 feet deep but is so clear that the bottom is visible from anywhere in the lake. The studies were published in a new paper in Freshwater Biology . The lead author, Cameron Barr, commented:


"It's like God's bathtub and is absolutely beautiful."

Great friends from Queensland have also visited Blue Lake on a holiday trip and taken a relaxing swim there. They mentioned the lake's beauty and felt themselves "blessed, delightfully clean, and rejuvenated but not necessarily struck down" by 
heavenly forces.

A swim in God's Bathtub sounds terrific to me no matter what the natural or celestial history.
