Overland Corner

The Overland Corner is a nature reserve managed by the National Trust of South Australia and is situated on the Murray River at the Heron Bend Cliffs. The limestones that make up the cliffs are full of fossil oysters, lace corals, sea urchins, lamp shells, snails, cones and cowries. The layering of the cliffs indicate the presence of a warm shallow sea some 15 million years ago and then the retreat of that sea around 5 million years ago, leaving a river and creek system in its place. There are three short self guided walks which take you to quarries where you can see the changing geology and fossils, with bonus Aboriginal sites like canoe trees and an ochre quarry and 19th century hotels, police stations and cemeteries.
