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.

Bedrock surface (T-T) at Site G30.

Access:

From Warburton - Woods Point Road.

Geomorphology:

The site includes road cuttings on the Warburton - Woods Point Road and the slopes adjacent to the Yarra River east of Crooked Creek. These comprise a complex of alluvial fan and channel gravels that rest on a truncated bedrock surface.

Significance:

State. The site clearly illustrates the process operative in the development of valleys on the Great Dividing Range. These include episodes of incision alternating with aggradation and channel filling, the fill being partly derived from alluvial fans and slope colluvium.

Management:

Class 2. Some quarrying of the gravels could be permitted as this exposes the contact between bedrock and overlying gravels. Other land use activities would not be compatible with maintaining the significance of the site.
