Protected from destruction in the early construction of Mona Vale Road, the small rock platform is right next to the busy arterial road. Two echidnas are weathered and a little hard to make out.
Nearby is an “indeterminate object” which has been documented as a snake by Sim – but has also been described as a shield.
About 30m away on a separate rock (D2) is another indeterminate figure. The engravings were thought to represent a hunting scene.
On the opposite of Mona Vale Road (and not documented by Sim or McCarthy) is a man with upraised arms.
