About this place
What to expect
Glacier Rock is a ~280 million year old Glacial Pavement carved into 510 million year old bedrock, exposed in the Inman River bed below the cafe. Also known as Selwyn's Rock, it's the largest of several glacial pavements created on the Fleurieu Peninsula by the Permian Ice Age. It's also one of the largest exposed glacial pavements in the world. The grooves, scratches and other glacial marks on the rock surface show that the icecap moved from southeast to northwest here. The riverbank above Glacier Rock contains boulders and other rock debris dumped by the melting icecap, including granites from Victor Harbor. The first European recording of Glacier Rock was in 1859 by ARC Selwyn, a geologist working for the colonial South Australian Government. It was the first recorded discovery of glaciations in Australia by European scientists. It was then rediscovered in 1897 by famous geologists Sir David Edgeworth and Dr Walter Howchin, from Sydney and Adelaide Universities. Glacier Rock is a designated Geological Monument that attracts geologists from all over the world.
