Byaduk tumuli lava blisters

Pretty close to the Byaduk caves are a couple of tumuli or lava blisters. The tumuli look like small piles of rocks and came into existence when the lava pushed to the surface. I guess, they are tiny volcanoes. Apparently, this phenomenon is pretty rare — there are only 3 discovered sites on earth with such lava blisters. Since most of the tumuli are on private ground, they are fenced it and can only be seen from some 100 meters away. So it was not the most impressive sight on the trip, but they are sort of on the way to the south

Byaduk lava caves

On the way from the Grampians to the coast, we stopped at the Byaduk lava caves about 20km south of Hamilton. The caves resulted from lava flowing from Mount Napier that cooled and solidified on the surface. When the lava ceased to flow underneath about 30,000 years ago, the hollow caves were left behind and eventually the thin surface crumbled and opened them up. There are two different sets of tubes of which the first one is easily accessible. It is a bit slippery on the way down, so solid footwear (and of course a torchlight) are a good idea.
