There is an information sign near Underground Creek. This section of the sign explains how the creek might have become "underground". Looking at the cliff and the fallen rocks before it, you can well imagine this process happening.

Bald Rock creek tumbles down from above on the left of the colourful wave-like cliff. It is briefly visible before it disappears beneath the boulders. The creek emerges on the right of the cliff to flow into a peaceful pool before continuing winding its way across Girraween.
