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.

Gravel bars (A) in river at Site G24.

Access:

From Healesville - Koo-Wee-Rup Road.

Geomorphology:

The river is deflected southward around a ridge of Humevale Formation sandstone and siltstone. This rock outcrops in the river bluff west of the Healesville Road. The bed load is of coarse material and there are gravel bars in the channel.

Significance:

Local. The site shows the characteristics of the river in the Woori Yallock and Warramate Hills sector of the floodplain where the valley is aligned along the strike of the Palaeozoic bedrock.

Management:

Class 3. Public access to the river is possible and could be improved by appropriate signposting and track construction. The geological characteristics of the site would not be damaged by increased use in this way.
