G33, G34 - Abandoned Incised Meanders

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 link) section of the Geological Society of Australia website for details of geological heritage reports, and a bibliography.

Abandines meander channel (A) with gravel-capped hill (H) as meander core at
Site G33.

Access:

From Woods Point Road.

Geomorphology:

The site encloses abandoned higher level meanders that lie on gravel terraces 10 metres above river level. Each has a low rounded hill at the core of the meander.

Significance:

Regional. The Two examples cited are easily accessible examples of the process of valley widening in the Upper Yarra Valley.

Management:

Class 2. G33 is more readily discerned than G34 and displays a sequence of gravel terraces, for example the hill forming the meander core is capped by fluvial gravels. land use at G33 should be compatible with maintaining the display of slopes and channels. No land use constraint is suggested for G34.
