Bald Hill (Kalkallo)

This information has been obtained from the report: Eruption Points of the Newer Volcanic Province of Victoria by Neville Rosengren. This report was published in 1994 and was prepared for the National Trust of Australia (Victoria) and the Geological Society of Australia (Victorian Division). The review of eruption points was based on an earlier unpublished manuscript Catalogue of the post-Miocene volcanoes of Victoria compiled by O P Singleton and E B Joyce (Geology Department, University of Melbourne 1970).

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 value. 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.

Bald Hill (Kalkallo)


Private land.

Grazing, bare, outcrop on lava flows around the base.

Type 9:

Composite lava and scoria volcano.

Bald Hill is a prominent composite cone of lava and scoria with a shallow west-facing crater. Lava flows are thin and restricted on the east and north but a thick flow extends from the southwest corner and covers a wide area to the south and west of the volcano. The volcano erupted on the crest of an existing hill in the Palaeozoic sedimentary bedrock, accounting for the prominence of the present Bald Hill.

357 m; 90 m.


A large topographic feature and an unusual example of eruption point shape being strongly influenced by pre-volcanic topography.
