How old is Mount Schank?
4,500 years ago
Mount Schank is a dormant volcano, originally errupting 4,500 years ago. Access the Mount from the Port MacDonnell Road. There is a picnic area with a shelter and toilets. The Mount and surrounding area was declared a State Heritage Area in 1992.
Is Mount Schank active?
Mount Gambier’s Blue Lake and the nearby Mount Schank are Australia’s most recently active volcanoes, having erupted about 5,000 years ago. With an estimated eruption frequency of once every 10,000 years, the likelihood there will be activity anytime soon is not high.
When did Mt Schank last erupt?

How were the volcanoes in Victoria formed?
Many of the younger volcanoes in Victoria and South Australia are maar volcanoes. Maar volcanoes are craters with low rims around them and are formed by intensely explosive interaction between magma (mixture of molten rock, crystals and gases) and groundwater.
How long does it take to climb Mount Schank?
At the bottom a sign tells you it’s a kilometre walk to the top and will take 30 minutes one way. We’re a retired couple and had to carry one of our older dogs and it only took 15 minutes to the top, so it’s not that hard.
How was Mount Gambier formed?
As the volcanoes rocked the earth over 5,000 years ago, lava caves formed, an array of cenotes developed and breathtaking lakes established the limestone foundation of Mount Gambier. This created a region that is truly unique.
How deep is the Blue Lake?
253′
Blue Lake/Max depth
Blue Lake is thought to be of an average depth of 72 metres, but in places reaches 77 metres deep. The crater rim measures 1,200 metres (3,937 feet) by 824 metres (2,703 feet). The lake itself measures 1,087 metres (3,566 feet) by 657 metres (2,155 feet).
Is maar a volcano?
A maar is a low-relief, broad volcanic crater formed by shallow explosive eruptions. The explosions are usually caused by the heating and boiling of groundwater when magma invades the groundwater table. Maars often fill with water to form a lake.
When were volcanoes active in Victoria?
The cluster of volcanoes in the province began forming about 4.5 million years ago with the most recent eruption believed to have been Mount Gambier, about 5,000 years ago. The province is still considered active and contains volcanoes among the youngest in Australia, alongside some in far north Queensland.
How were Australia’s volcanoes formed?
It is thought that the central volcanoes were produced as the Australian continent moved over a hot spot in the underlying mantle which melted through the plate to form the volcano. As the continent moved northward, the stationary hot spot formed volcanoes further to the south on the continent.
Can you swim in the Little Blue Lake Mt Gambier?
In short, it’s a volcanic sinkhole in the middle of a paddock that the public can swim in! The Little Blue Lake is located in the Kanawinka volcanic area between two dormant volcanoes, Mount Schank and Mount Gambier. Experienced swimmers only due to depth of water. Cliff jumping is dangerous and prohibited.
Is Mount Gambier a mountain?
Mount Gambier | mountain, South Australia, Australia | Britannica.
What kind of rocks are found at Mount Schank?
What rock types are found at Mount Schank. The rock types found at Mount Schank are Igneous rocks which include intrusive and extrusive rocks.
Where did Mount Schank get its name from?
It was sighted by James Grant on 3 December 1800 and named after Admiral John Schank, designer of Grant’s ship, HMS Lady Nelson. Mount Schank is part of the Newer Volcanics Province, which is the youngest volcanic field in Australia. Mount Schank erupted about 5,000 years ago, around the same time as Mount Gambier.
Is the Mount Schank volcano still active or dormant?
Mount Schank is a volcanic cone formed by explosive eruptions, pyroclastic flows and lava flows. A highly prominent volcanic cone, it is generally regarded as the youngest volcano in Australia and is believed to have been active as recently as 2,000 years ago. It is thus still classified as dormant and not extinct.
How old is the crater on Mount Schank?
Mount Schank erupted about 5,000 years ago, around the same time as Mount Gambier. It is a very basic ash cone and the base of the crater does not extend below the water table, so there is no crater lake as with those at Mount Gambier.
