Description

Mammoth Cave is the longest running tourist cave still in operation in the area. It is also the biggest of all tourist caves between Margaret River and Augusta. A short passage leads to a huge chamber with only little decorations. Further inside the cave the number of speleothems increases, but this is not a dripstone cave.

The tour through Mammoth Cave focuses on cave palaeontology and geomorphology in the region. Palaeontological work carried out in Mammoth has revealed specimens of many of the extinct megafauna, some are over 35,000 years old. Some 10,000 fossils were excavated in the cave. The remains of a Tasmanian Tiger (Thylacinus cynocephalus) were dated at 25,000 BP. Also a 50,000 year old zygomaturus jawbone that is embedded in the cave wall. There are no guided tours but visitors get a MP3 audio self-guiding system.
