An extensive rock platform runs parallel to the road from Umina to Patonga. Most of the platform is just reachable from the roadway heading north and following the Electrical Poles tracks before climbing 15 - 20 metres up a series of rock walls. At the centre of this platform is a natural watercourse and waterfall - not visible via Google Earth and quite dangerous to traverse. There are indications that this area may have accommodated many engravings however the natural run-off from the road has perhaps caused the platform to fill with sediment and allowed shallow rooted native tress/shrubs to cover the area like a carpet. A large Kangaroo tail-like engraving along with several axe grooves are still visible.
