68. Musk Creek - Terraces

This information has been developed from one or more of these publications:

  • Sites of Geological and Geomorphological Significance in the Westernport Bay Catchment (1984) by Neville Rosengren.
  • Sites of Geological and Geomorphological Significance in the Western Region of Melbourne (1986) by Neville Rosengren
  • Sites of Geological and Geomorphological Significance on the Coast of Port Phillip Bay (1988) by Neville Rosengren.
  • Sites of Environmental Significance in the Flood Plain of the Upper Yarra Valley Region (1983) by Neville Rosengren, Douglas Frood and Kim Lowe (as part of a study of Sites of Environmental Significance by the University of Melbourne for the then Upper Yarra Valley and Dandenong Ranges Authority).
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. See the Earth Science Heritage section of the Geological Society of Australia website (external link) for details of geological heritage reports, and a bibliography.

Escarpments and terraces, Musk Creek,
Site 68
Access:Musk Creek Road.
Ownership:Private land.
Geomorphology:The valley slopes of Musk Creek and Cotton Tree Creek have a series of benches or steps that lie along the contour of the slope and terminate as a minor escarpment. The lower scarp is most pronounced. The scarps were interpreted by Keble (1950) as erosion benches formed at stages in the development of incised valleys. They were seen by him as representing still-stands of the sea during periods of falling sea level. Other factors such as marine erosion and the possibility that these are structural benches formed on layers of hard lava need to be further investigated.
Significance:Regional. These are the best examples of valley side escarpments and terraces that occur in the Mornington Peninsula. They are of considerable importance in determining the evolution of the slopes of the Peninsula.
Management:Class 2. Close subdivision of the slopes that include the terraces should not be permitted. Building sites should not be allowed if they occur on the major slope changes with the terraces.
