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 (external link) section of the Geological Society of Australia website for details of geological heritage reports, and a bibliography.

Location:	355460. Three kilometres north – north-west of Boolarra South.	Sites 8121-2 to 7
Access:	Fishers Road off Grand Ridge Road.
Ownership:	Private land.
Geology/Geomorphology:	This is a large and complex landslip consisting of multiple rotational slumps in weathered Older Volcanics. The headwall scarps of the slumps lie below a narrow ridge and are approximately at the same elevation indicating that some weathering horizon or structure in the basalt determines their origin. The lower part of the slide material has diverted a small creek towards the western side of the valley. Most of the landslip is inactive although small movement on some of the slumps is apparent.
Significance:	Regional. This is one of the largest landslips in the Boolarra area.
Management:	Because of the area covered by the site, the value of the significant features is unlikely to be affected by localised land disturbance.
