12.3 Boggaley Creek Boulder Beach

This information has been developed from the publications:
  • 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 Geological and Geomorphological Significance in the Shire of Otway (1984) by Neville Rosengren.
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 (external site) section of the Geological Society of Australia website for details of geological heritage reports, and a bibliography.

Location:12-536217. Mouth of Boggaley Creek, three kilometres north of Wye River.

Boulder beach at Boggaley Creek.

Access:

Great Ocean Road.

Ownership:

Crown land.

Geomorphology:

A deposit of rounded boulders and gravels at the rear of the shore platform has been interpreted as an abandoned (and possibly emerged) boulder beach (Gill 1973). The boulders rest on an abraded rock surface that is a former short platform. Near the roadway the boulders are partly covered by soil and vegetation and are not now affected by wave action. They therefore were emplaced by waves that reached further inland than at present and their appearance suggests that this emplacement took place during the Holocene period.

Significance:

State. This is an important reference site for the study of stranded beach gravels with a view to determining Holocene sea level and storm wave conditions. No single accepted analysis of these conditions on the Otway coast has yet been advanced.
