  • 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 Environmental Significance in the Flood Plain of the Upper Yarra Valley Region (1983) by Neville Rosengren, Douglas Frood and Kim Lowe (as part of a study of Sites of Environmental Significance by the University of Melbourne for the then Upper Yarra Valley and Dandenong Ranges Authority).
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 section of the Geological Society of Australia website (external link) for details of geological heritage reports, and a bibliography.

Location:Labertouche - 905863. Two kilometres north of the Princes Highway at Longwarry north.

Access:

Morrisons Road.

Ownership:

Private land Crown Land.

Geomorphology:

The Bunyip River, at the junction of Two Mile Creek and Cannibal Creek is bordered by river terraces with well defined margins. The Bunyip is incised into the flood plain to a depth of five metres, and traces of the former higher level channels on the bordering terrace are very distinct. This phase of channel incision may be related to rejuvenation of the river following drainage and clearing of the former swamp lands to the south over the past century.

Significance:

Regional. The site is a clear example of the development of river terraces by an episode of stream incision.

Management:

Class 2. Further straightening of the river channel should not be permitted on this sector.
