I remember that deposit. Sometimes it may be small marsupials who start the deposit, sometimes big ones. Quite often they are abandoned and may have been for centuries. There are some spectacular, almost stalagmitic deposits of the black material in the Buyaduk lava tubes down near Warnambool and plenty over in the Buchan Caves as well. Often you can see polished rock, especially in fine grained stone such as limestone at the entrance to caves, where the animals have been rubbing, sitting and hopping over the same place for aeons. The one on 'The Bard' could be from 1st time leaders shitting themselves. |
