Mt. Gambier, South Australia
540 x 405 JPEG
Published August 30, 2008
Sitting near Australia’s rugged southern coast, the South Australian town of Mount Gambier is built on the side of an extinct volcano. The caldera of the volcano has filled with rainwater, forming a very deep lake that provides the town with water. The large caldera lake is called Blue Lake due to a rather peculiar characteristic: the water turns a brilliant cobalt blue during the summer and early fall.
