Mount Gambier

The landscape around Mount Gambier is defined by volcanic craters and limestone plains, which have shaped both the city’s layout and its role in the Limestone Coast economy. Blue Lake, set within an extinct volcanic crater, is the city’s defining geographic feature and an important water supply. The wider Mount Gambier Volcanic Complex records relatively recent volcanism in Australian geological terms. Groundwater has also formed caves and sinkholes beneath the area; Umpherston Sinkhole was transformed into a sunken garden by James Umpherston in the 19th century.
