ROCK IN PADDOCK NEAR WATERCOURSE

This rock could be the Shepherd's Rock, carved by Parkhurst lad and shepherd Richard Kirby, and located at Dumbarton, Toodyay.
The following description is from the Heritage Council of WA's inHerit database listing for "Shepherd's Rock, Place No. 2473" and appears to match some of the features evident in this photo.
"Physical Description
The large granite rock is located in the shallow valley of a watercourse. Large mature trees are present close to a narrow stream. The surrounding land is open pasture and sheep were grazing in the paddock in which Shepherd’s Rock is located. The rock is approximately 3 metres high and 3 metres wide at the base. The rock is roughly half of an oval in shape and the carving is located on the face which is oriented toward the stream. The carving ‘A.D. 1849 R. KIRBY’ following these letters are two symbols, a shepherd’s crook and a bottle. The carving is obscured by lichen growing on the surface of the rock but does not appear to be penetrating the surface and changing the form of the carving. The property continues to be used for sheep farming and presumably has changed little since the period in which the carving took place."
