These engravings are located on a steep section of the main rock platform at the top of a hill west of Bulls Hill Quarry. These engravings are similar to those that I have seen at Muogamarra Nature Reserve (Manta Ray Site) as recorded by W.D.Campbell in 1899.
Revisiting the Aboriginal Engravings of the Sydney / Hawkesbury Districts. 14 Blacks, 6 Tigers, 3 Death Adders, 8 Brown Snakes, one unidentified grey blue snake but no pythons ..... that would be about 42 serious reptiles for more than 511 engraving platforms and a few caves - INXS of 7636 engravings, still counting and still loving it!!!
Yep ...we are all still patiently waiting for the day when the people from world's oldest continuing culture, holding the same legal rights as a rock on a track before 1967, the traditional owners of this land, are at least acknowledged in the Constitution of Australia as part of the development of a treaty and edge closer to true reconciliation.
