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:15-959132. One kilometre south of Burrupa.

Access:

Gellibrand River Road.

Ownership:

Private land.

Geomorphology:

The Gellibrand River has developed an entrenched valley at the base of which is a flood plain only 50 m wide. The channel meander amplitude is identical with that of the valley sides and the river has well defined levee banks.

Significance:

Regional. This river section illustrates three phases in the development of the lower Gellibrand valley i.e. low sea level stages with rapid valley down cutting; higher sea levels with alluviation and tidal flow transmitted through the channel; renewed down cutting to produce the slight entrenchment of the modern floodplain deposits.
