The Australian plate is at the moment relocating inside a northward direction And through enough time of the primary volcanic action, the Mount Gambier region moved around a hotspot known as the East-Australian hotspot.
Mount Gambier is rich in caves as a result of location’s distinctive geological historical past. It’s Found around the Limestone Coast, a location characterised by porous limestone rock. As time passes, rainwater’s sluggish and continual dissolution of the limestone has produced quite a few underground caves and sinkholes.
The reason for the blue seasonal adjust is not correctly understood. The main concept retains that when warmer temperature delivers the higher layers with the lake earlier mentioned 20° Celcius (sixty eight° Fahrenheit), the solubility of calcium carbonate in the drinking water decreases. The calcium carbonate precipitates out of the h2o and types micro-crystals, which scatter blue light-weight. Because A great deal in the area bedrock is limestone (compressed calcium carbonate), There exists an enough provide of calcium carbonate to dissolve into your water.

Kate Satisfy Kate. She will be the founding father of one among Australia's most popular and practical journey planning communities, where by she shares trusted details and exclusive savings.
In winter, the floor waters great, not just allowing for far more calcium carbonate to dissolve back into your drinking water, but will also breaking down the thermal stratification on the lake waters, permitting the cooler plus more calcium carbonate-prosperous water further in the lake To combine Using the area water. A further likelihood would be that the colour is caused by plankton and micro organism within the drinking water, which turn out to be additional active with for a longer period, sunnier days and hotter water.

Step into a world of wonder when you undertaking deep in the underground passages adorned with amazing limestone formations. The mesmerizing Exhibit of stalactites and stalagmites evokes a way of awe, even though the well-informed guides share the cave’s intriguing background and geology.
When diving demands permits, the viewing System provides breathtaking sights for individuals who want to remain dry.
This volcanic intricate was made all over four,000 yrs in the past. The world's shallow drinking water table was heated through the volcanic activity, creating steam stress to create in the course of eruptions. This designed the characteristic craters (maars) and steam vents in the area.
Even so, on nearer assessment, the clarity of the water arrives into concentration. You might even witness competent divers volcano mount gambier rising with the depths. This enigmatic sinkhole is a favourite amongst abseiling cave divers.
In 1839, Stephen Henty, one of several Henty brothers who occupied substantial landholdings at Portland and Merino, led an overland expedition to examine the Mount Gambier area. He was the primary white male to climb the peak and examine the blue crater lake.[7]
Sinkholes in Mount Gambier are shaped due to the region’s limestone bedrock slowly and gradually eroding over time. This erosion is attributable to groundwater that seeps from the rock, dissolving it and creating underground caves. At some point, the roof of those caves may perhaps collapse, making floor depressions or sinkholes.
"In order Australia moves northward, you will get that north to south line together the east Coastline Australia of particular volcanoes, and since it moves clear of that scorching spot, it just stops.
