Caves in Tasmania



Did you know that Tasmania is home to the deepest and longest caves found in all of Australia? From  Mole Creek to Junee Florentine, the caves found in Tasmania offer stunning view of glow worms and stalagmites galore where adventurous tourists venture into these holes in the ground. With a constant temperature of 9 degrees F, the Mole Creek Cave's climate is unchanging regardless of the outside temperature. That being said, whether summer or winter, the caves are the perfect place to visit. 
Tours offered in the cave include viewings of the underground rivers that have formed these natural wonders as well as the glowworms that call the cave home. 
Reserved as national park in just 1996, Mole Creek Karst is the newest addition to the land reserves found around Tasmania. Two of the biggest caves are Marakoopa and King Solomons Caves although these are only 2 of the 300 known caves and sinkholes found throughout the "karst" landscape (the actual definition is "landscape underlain by limestone that has been eroded by dissolution, producing ridges, towers, fissures, sinkholes, and other characteristic landforms.")
These caves formed a long time ago during the Ordovician Period (400-500 million years ago). When Tasmania was part of Gondwana, the land was closer to the equator and covered by a warm, shallow sea. Limestone was deposited as coral reefs and as the land eventually developed, streams and rivers formed the iconic karst landscape full of the various caves we see today.
Because the caves undergo decomposition slowly, this area serves as a window into the geographic and anthropomorphic past of Tasmania. Whether records about the evolution of the Earth or lifestyles about the aborginal people that lived in these caves 40,000 years ago, these caves are an amazing resource for historians and geologists alike.

  2. Caves are amazing, not only in terms of visual beauty, but the natural geological formations they hold! I would like to think that many of these caves formed due to changes in sea level. Perhaps the places they are located were once found underwater, and hydro-erosion took its toll?

  3. I'm definitely down for some spelunking! I wonder if we'll see any cave paintings like we saw in the presentations about the thylacine?
