I recently visited Mammoth Cave on our stay in Margaret River. As a local, I’m lucky to visit the area numerous times a year and explore the attractions. The Margaret River caves are one of my favourite tourist attractions.

Mammoth Cave, in the Margaret River region, is an impressive limestone cave with a fascinating geological history.

Mammoth Cave Geology

The Margaret River region sits on the Leeuwin-Naturaliste Ridge, composed mainly of limestone – a sedimentary rock primarily made up of the remains of marine organisms such as coral and shells that accumulated on the seabed over vast periods. These accumulated remains underwent compaction and cementation, turning them into solid limestone rock.

The area has a karst landscape, which is characterised by the dissolution of soluble rocks like limestone, forming various underground landforms such as caves, sinkholes, and underground rivers.

Rainwater is naturally slightly acidic due to the presence of carbon dioxide. As it percolates through the soil and into the limestone, it starts to dissolve the calcium carbonate present in the rock.

Over thousands of years, the mildly acidic rainwater slowly dissolves the limestone, creating tiny cracks and fissures in the rock.

As time passes, these cracks enlarge and eventually develop into larger passages and caverns, such as Mammoth Cave. The cave formation process is ongoing, with the cave still evolving and changing, albeit at a slow pace.

Mammoth Cave Features

Stalactites and Stalagmites

The dissolution of limestone not only creates caverns but also stunning formations inside the cave.

Water droplets seep into the cave from the surface, carrying dissolved calcium carbonate. As the water drips from the cave ceiling, it leaves tiny calcium carbonate deposits behind.

Over time, these mineral deposits build up and form stalactites hanging from the cave ceiling. Similarly, as water drips to the cave floor and evaporates, it leaves behind mineral deposits, resulting in stalagmites that grow up from the cave floor.

Perennial Stream

Water continues to play a vital role in shaping Mammoth Cave. A stream flows through the cave during winter and spring, further eroding the limestone.

At Mammoth Cave in Margaret River, fascinating fossils provide a glimpse into the region’s ancient past. The cave’s name might evoke images of prehistoric giants, but it is not named after mammoths; instead, it was dubbed Mammoth Cave due to its size.

However, the cave has yielded significant paleontological discoveries. Over the years, scientists have uncovered the remains of ancient animals, including marsupials and extinct megafauna that roamed the landscape thousands of years ago.

My Experience with Mammoth Cave

mammoth cave boardwalk to cave surrounded by forest

In the Visitor Centre, I was provided with an audio guide with information on how to use them. Then I was on my own to explore Mammoth Cave!

This cave is an excellent attraction if you have young children who often become bored on guided tours. As this is self-guided it allows families to explore the cave at their own pace. Please note, though, that strollers are not allowed in any part of the cave, including the first accessible chamber.

Leaving the building, I followed a wooden boardwalk to the cave entrance, which continues into the first chamber, making it fully accessible for wheelchairs.

You can see the stream (in winter and spring) from the walkway and the incredible limestone formations. The dim lighting added an ethereal glow to the majestic stalactites hanging from the ceiling like icicles and the stalagmites rising from the floor, seemingly reaching out to touch the ceiling above.

The audio guide’s explanations brought life to the formations, describing how the slow and steady dissolution process had sculpted these intricate shapes over millions of years. It was amazing to see the delicate shawls and the awe-inspiring columns, each with its own unique story of creation.

As I climbed the stairs and moved through the chambers, hearing about the ancient Australian Megafauna fossils, including the 50,000 year old ‘’zygomaturus’ jawbone, was interesting.

Eventually, the boardwalk lead to the base of a large doline where I exited amongst the forest. It was amazing to see towering trees growing on top of the cave.

From there, I followed the Marri Walk Trail and was astounded to see how well the forest was recovering after the recent massive bushfire. New plants were regenerating; I even saw many orchids on the trail.

This experience was educational and family-friendly, perfect for children and adults. I left Mammoth Cave with a sense of awe and gratitude for having had the opportunity to witness such natural splendour.
