Summary: An interesting Aboriginal engraving site in Calga, which includes hunting weapons and two squid, and a very large number of grinding grooves.

Partly destroyed by the construction of Peats Ridge Road in the 1970s, this Aboriginal engraving site includes a number of weapons as well as two squids, and a large number of grinding grooves.

The two larger of the figures described as squids was documented as having eight transverse lines, of which seven can be clearly seen.

The smaller squid has eleven, distinct transverse lines.

Next to the smaller squid are what appear to be two weapons – a womerah and a club – and a smaller indeterminate object.

At the northern edge of the platform and damaged both by the rock platform being cut away for the road and by graffiti (which was done in the 1960s or 1970s) is a very long and narrow figure: “a straight indeterminate object 11 feet long”.

In the middle of this long figure is an engraved circle.

Most of the grinding grooves documented by Sim on this platform are buried, but there is a small set and an additional single groove at the southern end that can still be seen.

An adjoining platform to the east has more engravings, but it’s hard to determine what most of them represent. There are two bird tracks, which are fairly distinct.

The other fairly clear figure may be an slender eel.

There are a number of lines showing clear punctures, which represent a larger figure that has partly weathered away.

To the south-west on a separate platform is a very large number of grinding grooves.

Over 150 were counted in the 1940s when the site was first documented.

A review of different techniques for photographing Aboriginal rock art. This includdes oblique flash, chain and planar mosaic imaging which combines hundreds of overlapping photos.
Yengo National Park was an important spiritual and cultural place for the Darkinjung and Wonnarua People for thousands of years, and 640 Aboriginal cultural sites are recorded in the park and nearby areas.
Over 40 sites have been recorded within the park; many were located along the river bank and were flooded by the building of the weir in 1938.
Hornsby Shire - which is the largest LGA in the Greater Sydney Metropolitan region - contains approximately 600 recorded Aboriginal rock art sites (and over 1,200 Aboriginal heritage sites). These date back from thousands of years to post-European contact art.
