[QUOTE="user 4386, post: 647967, member: 4386"] A couple of minor points of correction - if you will excuse (but I have photographed the erratic myself and have studied the granodiorite (including cutting microscope sections of it and published on it) - starting in the 1960s, the last time in the 1990s. 1. It is the Stranger erratic and is west of Heathcote near the resorvoir at Derrinal/Knowsley East 2, I think the place is called Cosbie, not Crosbie that contains the granodiorite that PROBABLY supplied the erratic at Derrinal 3. The Cosbie granodiorite is not unique but one of many similar granodiorites of Late Devonian age in central Victoria. This is from an earlier (Permian - 200 million years) ice age to the one I discussed above in Tasmania (the Tasmanian one being from a glacial interval in the present ice age that started less than 2 million years ago, the glacial interval only being around 50,000 years ago. The aborigines would have seen the glaciers there.
