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:	400945. Two kilometres north of Tubbut.	Site 8623-6
Abstract:	Outlier of Tertiary Older Volcanics.
Access:	Track through private property from Tubbut.
Ownership:	Private property.
Geology:	Several flows of olivine rich Lower Tertiary basalts outcrop at Basalt Hill. The lowest flow is highly weathered producing deep red soils while the upper flow is less completely weathered and consists of rounded basalt boulders. The location of the eruption points of the Older Volcanics is unknown. The basalts of this are overly fine grained adamellites.
Significance:	Local. Exposures of Tertiary Older Volcanics east of the Snowy River are highly weathered and occur as isolated hilltop remnants. The Basalt Hill exposure is typical of these deposits.
Management:	Because of the area covered by the site the value of the significant geological features is unlikely to be seriously reduced by localised disturbance, e.g. road works, extractive industries or agriculture. Limited quarrying map in fact enhance the geological significance by providing additional exposure.
