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.

Abandoned channel patterns (A), and straight channel
reach at Site G26. arrows show edge of terraces.

Access:

Station Road.

Geomorphology:

A three kilometre reach of the Yarra River below Millgrove is flanked by terraces on the northern bank. The terraces are not present south of the river. The lower terrace surface displays a complex pattern of anastamosing relict channels that contrast with the modern long straight channel pattern. The site is of particular interest for the absence of meanders.

Significance:

Regional. The long straight channel sector is unusual and contrasts with the well defined meander patterns downstream.

Management:

Class 2. Close subdivision on the terrace margins and the areas of abandoned channel on the north of the river would essentially obscure the significant geomorphological features of this site. Maintenance of present land use intensity is preferred.
