Lava Blister (Williamstown)

Volcanoes on Point Gellibrand? Well, not quite, but the Gellibrand Point is home to an intriguing volcanic phenomenon. Many millions of years ago, Melbourne's west was alive with volcanic activity.

As lava flowed towards the (now) shoreline of Point Gellibrand, there was a build up of gases within the hot magma and a large bubble measuring about 3 metres in diameter was caused. The curved roof has collapsed, but the sides remain, and form a circular shape amongst the rocks. This strange formation is extremely rare and has fascinated geologists the world over. Victoria's basalt plains form one of the largest lava plains in the world.

The blister is located along the shoreline next to a walking path about 100m from the playground along Battery Road.
