126. Strzelecki - Lang Lang Valley

This information has been developed from one or more of these publications:

  • Sites of Geological and Geomorphological Significance in the Westernport Bay Catchment (1984) by Neville Rosengren.
  • 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:
Poowong - 995574. Eight kilometres east of Poowong.

Image: Sites of Significance Port Phillip Bay
Small potholes in channel incised into
Mesozoic rocks.

Access:
Waterfall Road.

Ownership:
Private land.

Geomorphology:
The Lang Lang River and a tributary are incised into Mesozoic sandstones which are exposed in the channel for several hundred metres adjacent to the old Strzelecki railway line. The streams flow across the strike of the gently dipping sandstones, thicker or more resistant beds causing development of small falls and cascades. At these falls, potholes are common and coalescence of these is the main form of channel incision and widening. There is little sand in the channel, the bank materials are a mixture of pebbles and boulders derived from outcrops in the channel and clays delivered by slope wash. Short alluviated sectors with some degree of incision alternate with the bedrock reaches.

Significance:
Regional. The site is one of the few extensive bedrock channel sectors in the Lang Lang River valley. The river gradient is steeper than other headwater tracts.

Management:
Class 1. Reservoir construction, quarrying, or any action that would obscure the form of the channels and the rock outcrops should not be permitted.
