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.

Location:Corinella – 618477. 300 m west of the jetty at Corinella.
Image: Sites of Significance Westernport Bay
Weathered basalt platform surface (arrowed)
overlain by beach gravels and shells (A).
At the top is a midden (B).
Access:Corinella Road.
Ownership:Crown land.
Geomorphology:A deposit of stratified sediments at the foot of the bluff includes a variety of minor gravel, sand, shell and clay. A section of the material in a wave-cut low cliff includes two distinct horizons containing shells. Jenkin (1961) and McMickan (1977) interpreted the lower shell bed as a former beach built at a sea level one to two metres above present sea level, and the upper bed as a kitchen midden. However, given that the deposit is now being eroded by occasional storm wave action, it is likely that the lower bed simply represents deposition at a time of more vigorous wave action in the past and is not necessarily an emerged or raised beach deposit.
Significance:State. The site is one of several in Victoria used to interpret Holocene sea level history. It is readily accessible and provides an important field locality for teaching and research in coastal studies.
Management:Class 1. Activities that will damage the site in any way cannot be permitted. These include roadworks excavation, coastal protection structures, and dumping of material on the slope foot deposits and the adjacent bluffs, cliffs and shore platforms.
