7.4 Parallel Ridge and Valley (Pliocene Ridges)

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:7-995327. Nine kilometres south east of Simpson.

Access:

Crescent Road.

Ownership:

Mostly private land and some Crown land (Road Reserve).

Geology/Geomorphology:

This site is a clear example of parallel drainage aligned north- north-west. This pattern is typical of the north-west of the shire and is also represented (and discussed) on
Sites 6.1 and 7.2. There are extensive old landslip scars on the valley sides and a site of possible stream capture is indicated.

Significance:

State. The difference between this site and
Site 6.1 is in the material comprising the ridges which here is not Moorabool Viaduct Formation sands. The drainage pattern may have been superimposed from overlying deposits (since eroded away) but as at Site 6.1, further work is necessary to explain these features.
