1.3.4 Karst with depressions (Buchan)

1. Eastern Uplands (EU)
1.3 Landscapes below 500 m of low relief

As in New South Wales, the Victorian highlands include relatively small enclaves of limestone in which caves and other karst terrain-elements have developed.

The main outcrops at Buchan / Murrindal comprise one of the largest areas of cave-forming limestone in eastern Australia with “The Potholes” having the highest density of dolines in any Australian karst system. Solution effects, including collapses into a complex system of caves reflect drops in cave stream levels and in the water-table levels associated with the down-cutting of the nearby Buchan River.

Smaller cave areas occur on the Snowy River and Limestone Creek (northeast of Benambra).
