Answer:
Mount Gambier
The volcano of Mount Gambier was formed around 4900 years ago, while the city of Mount Gambier was settled around 1840. The volcano is now dormant, and a lake fills what was the volcano's crater. This lake, known as the Blue Lake, undergoes an amazing transformation each year, changing from a dull grey to a brilliant turquoise blue each November to March. The southeastern region of South Australia is known for its limestone caves and Mount Gambier is no exception, with Cave Gardens located in the centre of town in a park opposite the town Post Office. The cave featured in the Cave Gardens display was once the water source for the town, with water being pumped up from its base.
