Southwest Riverstone

Our Quarry

The quarry is situated on the highest point of the landscape in an ancient glacial bed which overlooks the Blackwood river. Most people are surprised when they find out it is dug from the top of a hill and not out of the river. The deposit is the result of an ancient glacier that was moved here from possibly from what is now Antarctica.

Our Stones

The stones are rounded and smooth, initially from being pushed along by a glacier then later due to the action of enormous volumes of water running over them as a result of melting ice. The glacier bed is considered to be one of the major drainage basins for the South west at that time running from south of the Stirling Ranges to off the Darling Scarp near Kirup.

The stone is embedded in kaolin clay which is a very fine white clay used for porcelain making and whitening paper. Kaolin is formed by the weathering of feldspar. Due to the harsh actions of the tumbling stones and massive glacial fluvial flows that occurred, no fossils have been found and not likely to.
