The evidence for two very different geological events is
recorded in the rocks of Fossil Cove.
The lightly coloured Permian Mudstone is around 250 million
years old. This fossil rich rock was very much closer to the South
Pole when laid down as unconsolidated sediments.
About 180 million years ago, as great upheavals took place,
molten rock forced its way upwards, displacing and deforming
existing rock. This process of displacement has helped move and
shape the Australian Land Mass to where and how we see it
today.
The dark coloured dolerite, or blue metal as it is commonly
known, in the Fossil Cove area, is in fact, some of that previously
molten rock.

This cache is in a beautiful area only 500 metres down a bush
track. There are a lot of stairs though, so be prepared! Please do
not remove any of the fossils, but you can take photos and post
them!
