Located just above the top of the Great Sand Dune on the eastern side of the Rock.

The “Mammoth” name reflects the size of the cave – the alternative “Signal Station” refers to the fact that it was just below Signal Station. It is located above the water catchments with another 20 to 25 metre climb to reach the mouth of the cave. It is known to be one of the biggest caves in the area.
