Geological heritage sites, including sites of geomorphological interest and volcanic heritage sites, are under regular revision by the Geological Society of Australia, especially in the assessment of significance and values. Reference should be made to the most recent reports.

Location:

180860. 13 kilometres north-east of Sale.

Abstract:

Abandoned alluvial and swamp deposits.

Access:

Clydebank Road.

Ownership:

Private land.

Geomorphology:

The plain east of Sale is an alluvial plain formed by delta and flood plain deposition from distributaries and prior channels of the Avon and Macalister rivers. Several conspicuous ridges rise 5 to 6 metres above the flat and swamp surface of the plain and mark the courses of former streams. The ridges consist of silts and silty sands of fluviatile origin and in places they appear to have been re-arranged and are capped by wind-blown sands. The ridges probably originated as levees and owe their relative height to differential compaction of the adjacent clays and peaty clays of the delta plain, and to addition of dune sands. Lakes such as Melanydra and Kakydra occupy areas of impeded drainage between ridges.

Significance:

Regional. The fluvial ridges are confined to the area south of the Avon River and illustrate a phase of Pleistocene alluviation not evident further east.

Management:

Limited removal of the sands of the ridges would not detract significantly from the interest of the site, however ridge sections along the road reserve should not be removed by quarrying.
