The bottom is a haven of humidity and plants, and consists of two parts.
The first is level with the desert, and a path winds between rocks, gum trees and spinifex grass balls which catch the light.
The second part is halfway up between the desert and the top of the hill, and is called the Garden of Eden. It is a closed place sheltering gum trees and cycads—“fossil” ferns which can live for more than a thousand years.
I’ve taken these shots from above, using the sky and rock reflected in the water as a background, which makes them look weird.
On one of them, you can see how gum trees can “kill” one of their branches (the black one) to consume less water during droughts.
