The Circles along the Oaks Trail in the Blue Mountains (near the junction of the Woodford Range and Western Ridge) once had an Aboriginal stone arrangement consisting of a circle of stones. There is no longer any trace of these. What does still remain are four concentric circles engraved on a sloping section of a rock platform.
They were first documented in 1940, and have been described as unique in the Sydney-Hawkesbury region. (There is a similar motif along Linden Ridge at the Linden Ridge Echidna and Fish engraving, which is thought to be a “doubl-echidna”.)
Near the engraving is a set of five grinding grooves next to a pothole.
A short distance away are two more axe grinding grooves, next to another pothole.
(Another two sets of grinding grooves were destroyed in the construction of The Oaks firetrail.)
