Hanging Rock.  Mount Diogenes

 A reserve since 1886 it is steeped in Aboriginal history & for a while it was a hideout for the notorious bushranger, Mad Dog Morgan. It is an extinct volcano of the type known as a "mamelon". Made of a particularly thick lava that, when cooling, produced vertical fractures and the distinct pinnacles, deep crevices and massive rocks. This site is believed to be six million years old. The rock is called solvsbergite, only found in Norway, Sweden - and Hanging Rock.
