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.

Granite slopes and steep stream channels at Spion Kopje.

Access:

Limberlost Road via Pioneer Creek Road.

Ownership:

Crown Land.

Geology/Geomorphology:

This site includes sufficient area to display the typical terrain of the Tynong Granite, the dominant lithology of the northern part of the Westernport Bay catchment. The peak of Spion Kopje (898 metres), is the highest point in the catchment. The site includes Spion Kopje Creek and Black Butt Creek and their tributaries as these streams show parallel alignments that strongly reflect control by the major joint systems in the granite. There are a number of granite outcrops and steep stream channels sectors.

Significance:

Regional. The site is a major example of the terrain and geology of the northern part of the Westernport Bay catchment.

Management:

Class 2. Timber extraction and quarrying activities should be excluded from the area of the site.
