This information has been developed from this publication:

Sites of Geological and Geomorphological Significance in the Western Region of Melbourne (1986) 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 section of the Geological Society of Australia website for details of geological heritage reports, and a bibliography.

Location:	Lerderderg - 697264. Shire of Bacchus Marsh. Northern side of Werribee River, 4 km west of Bacchus Marsh.	Tabletop - Landslips
Access:	Werribee Vale Road.
Ownership:	Private land.
Site Description:	Tabletop hill is capped by a remnant of Newer Volcanics basalt which overlies sediments of the Werribee Formation. The southern hillslope includes an extensive area of mass movement including rotational slumps and earthflows. Other extensive mass movements occur on the opposite valley slope valley above the alluvial floodplain of the Werribee River.
Significance:	Local. The site is an example of the extensive mass movement processes which have developed the broad valley of the Werribee River below the Werribee Gorge.
Management:	Class 2. The site should be retained as an active mass movement feature and land management should be adapted to take account of the potential hazards of the site.
