Summary: An Aboriginal engraving site near Collingridge Point has three motifs and a number of axe grinding grooves - as well as non-Aboriginal dinosaur carving,

In thick scrub above Collingridge Point is Ploddy the Dinosaur, a non-indigenous engraving of unknown provenance. Perhaps it was carved whenthe scrub was less thick, and the rock platform easier to reach. One theory espoused by bushwalker Anthony Dunk (which makes a lot of sense) is that it was carved by the artist and writer George Collingridge, whose house was built just below here at Collingridge Point in the early 1880s. “The dinosaur species depicted, Diplodocus, was first discovered as fossils in 1877, so the timeline fits with Collingridge moving to the area”.

Near the dinosaur carving are a small number of Aboriginal engravings. The most obvious are two fish, which are next to each other.

A short distance away is an indeterminate figure, which looks like an oval with a ear or tail.

A small waterhole has a number of axe grinding grooves next to it – many now covered by vegetation.
