Other significant places including Lake Mungo featured in my exhibition are found in Nitmiluk and Kakadu National Parks, the Karijini National Park and at Point Roadknight, a small promontory along The Great Ocean Road.

Along the sides of the Katherine Gorge passages of sediment configured in ways that reminded me of ancient texts in stone.

As oxygen entered Earth’s atmosphere it caused iron laden sediment in the ocean to rust, fall to the sea floor and over eons compress into The Banded Iron Formation found in the Pilbara. In this etching – intaglio and chine-colle I imagined the process of sedimentation.

A  mineralised root system, part of the Point Roadknight promontory, called the “Petrified Forest” resembled an ancient ruin complete with columns, portico and entablature. Now non-existent due to high winter tides, sea spray and wind.
