Alligator Gorge

Alligator Gorge. The powdery sediments forming the walls of the Gorge were laid down by glacial outwash when Australia lay astride the equator about 600 million years ago. This shallow-water marine deposit accumulated on a continental shelf at the eastern edge of a continent that was little more than half its present size and looked like Antarctica does today.
