Summary: An large rock platform near Bilpin, which has approximately 100 Aboriginal grinding grooves and several engravings.

First documented in the 1960s, this extensive rock platform on the edge of Wollemi National Park contains about a hundred Aboriginal axe grinding grooves and several engravings.

Most of the grinding grooves are located around multiple waterholes on the sloping platform.

A few grooves are partly covered by encroaching moss; of the orginal 100 recorded by Ian Sim, about 85 are currently visible and more are likely covered by vegetation.

At the southern end of the rock platform is a dense cluster of grooves in a creek bed.

The engraved figures are mostly indeterminate; a kangaroo track is next to a curved line, which may be part of a larger (weathered) figure.

A long pecked channel is in the middle of the platform.

A circle may be natural, but appears to be pecked.

To the north of the rock platform on a ridge-top site are three more grinding grooves.

To the south along a small creek are several more grooves.

Aboriginal Sites by National Park

The Greater Blue Mountains World Heritage Area protects over 3,000 known Aboriginal heritage sites, and many more which are yet to be recorded. This area includes the Blue Mountains National Park, Gardens of Stone, Wollemi National Park and Yengo National Park.
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.
