South Australia's town of volcanic lakes
27.02.2013 - 01.03.2013 24 °C
We left Killarney and stopped for lunch at Lower Glenelg National Park. We decided not to camp there and travelled further across the border into South Australia, changed our clocks back 30 minutes (strange time zones in SA and NT!) and drove to Mount Gambier and stayed here for a couple of days.
This is our second visit to South Australia on this tour. We visited it briefly for 6 days in July 2012, travelling through Coober Pedy, Lake Eyre, the Oodnadata Track, Marree and the Birdsville Track. This time our stay in South Australia will be about 38 days.
Mount Gambier is famous for its 'Blue Lake' which changes colour dramatically each year. The Blue Lake is just one of the lakes within the three craters of the inactive volcano also named Mount Gambier. During December to March, the lake turns to a vibrant cobalt blue colour, returning to a colder steel grey colour for April to November. It is generally considered likely that it revolves around the warming of the surface layers of the lake during the summer months to around 20 degrees Celsius, causing calcium carbonate to precipitate out of solution and enabling micro-crystallites of calcium carbonate to form. The less colourful Valley Lake has a delightful recreational area with lots of birds and wildlife to watch.
From Mount Gambier we will travel north-west along the Limestone Coast to camp in Little Dip Conservation Park and/or Coorong National Park.
