What is the history of Jenolan Caves?

In the 1880s, Jenolan began to emerge as a genuine tourist destination. Jeremiah Wilson, an extraordinary caver, had explored to the end of the Elder Cave. In 1879 he had descended a shaft and rockpile to discover the ‘Imperial Cave’. This was soon followed by the discovery of the ‘Left Imperial’ cave in 1880.

How the caves were formed?

Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.

What type of landform is Jenolan Caves?

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.

How old are Jenolan Caves?

53, 377-405), scientists from CSIRO, the University of Sydney and the Australian Museum showed that Jenolan Caves has been existing and changing for at least 340 million years. In 1999 geologists estimated that the caves might be between 90 and100 million years old.

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.

What are caves and how are they formed?

Between the layers of rock and inside the joints, the water slowly dissolved away the rock. This made a large water-filled space. As the Current River cut its river valley, it cut down through the rock layers until it opened up the cave. This let the water out and gave us an air-filled cave.

What is cave formation?

cave, also called cavern, natural opening in the earth large enough for human exploration. Such a cavity is formed in many types of rock and by many processes. The largest and most common caves are those formed by chemical reaction between circulating groundwater and bedrock composed of limestone or dolomite.

What is Jenolan Caves made of?

At Jenolan, the limestone includes the remains of a coral reef, though it is composed mainly of fine grained calcite (lime mud). Over millions of years, these sediments become buried under layers of volcanic rocks, formed when solid matter from explosive volcanic eruptions fell into the sea.
