The Lucas Cave

As well as forming Caves, boombi is also essential to Aboriginal Culture. No journey made in Australia’s harsh climate could stray far from water. Waterways were therefore of great importance and watersheds and mountains marked clan boundaries.

Connecting to Country in the Jenolan Caves Australian Indigenous culture has revered the site as sacred for many hundreds of thousands of years, as the crystal waters in the caves and rivers surrounding the base of the limestone mountain are thought to contain healing powers.

“The cave was used predominately as a hunting shelter between about 50,000 and 30,000 years ago before becoming a residential base for family groups after 10,000 years ago. It was abandoned by about 7,000 years ago when rising sea levels finally cut it off from the mainland,” he said.

Jenolan Caves are the largest, most spectacular and most famous caves in Australia. Explore the world’s oldest caves – one of the most outstanding cave systems in the world. Experience Australia’s Most Spectacular Caves. Jenolan is not only the world’s oldest cave system, but is Australia’s…

For those travelling on a budget, I’d suggest not to go inside the caves. Well, at first this suggestion seems absurd, but look at this, the minimum cost per person is $30 and a guided tour is must to see the caves from inside.

Jenolan, with its caves, underground rivers and natural archways, is an example of a type of landform called “Karst”. Karst landforms occur where rock is easily dissolved in natural waters (fresh). Karst landforms are typically found in limestone areas.

Concentrations of carbon dioxide increased with the presence of tourists. In apparently well-ventilated sections of the cave system, carbon dioxide rose from pre-tour levels of 400 ppm to a daily maximum of 1000 ppm: in a less well ventilated cave, levels increased from 400 ppm to 1500 ppm.
