D1 Aitken Hill (Mount Yuroke) - Eruption Point

This information has been developed from the publications:

  • 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 Geological and Geomorphological Significance in the Shire of Otway (1984) 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 (external link) for details of geological heritage reports, and a bibliography.

Site Description

The site is an eruption point in the Newer Volcanics with a summit elevation of 265 metres. It is a composite volcanic cone built of scoria and lava flows with scoria predominant on the eastern side. At the summit is a V-shaped wall of basalt three metres high and two metres wide which remnant of a lava plug. Several lava flows issued from this plug including blocky and ropy lava and scoria.

Significance

Regional. The eruption point is one of the closest to the metropolitan area and is readily distinguishable as a volcanic feature. It is an example of the major geological process that has shaped the terrain to the north of Melbourne.

Management

Class 2: To maintain the distinctive form of the volcano and to preserve the summit plug and erupted rocks, it would be necessary to limit building on the hill to below the 230 metre contour. Quarrying of the summit area should not be permitted. Structures that project to or above the summit would also detract from the significance of the feature.
