On the side of what was once called Sugarloaf Hill and near the top of Powder Works Valley is a single Aboriginal engraving.
It may be a wallaby or kangaroo, and has a long kangaroo-like tail. But the shape of the head doesn’t look that of a kangaroo, and has what looks like two fins. So it may be a marine creature, a poorly drawn kangaroo or a hybrid of the two. Three nearby sites also have kangaroos, none of which are drawn like this – the Caleyi Trail Kangaroo, Caleyi Trail Kangaroos and Powder Works Valley Engravings sites.
Near the kangaroo / marine creature is very weathered engraving of a boomerang.
