Type 9: | Composite scoria cone overlying lava flows. | |
 | This is a large composite volcano of scoria and lava with over 200 m of local relief. The summit of dome-shaped without a major crater. It is reported that a small open spatter vent 8 m deep with a 1 m wide entrance occurs at the summit. There are two prominent parasitic vents - the larger at the southwestern base of the mountain and a smaller one on the northeastern flank. Lava interbedded with the scoria outcrops on the western slopes and there are extensive lava flows to the north. Blocks of Ordovician country rock occur in the ejecta. Perfect augite crystals up to 1 cm in length have been collected from the volcanic ash of this volcano. The slopes of this mountain have an established radial gully network. Deeper and broader gullies may have been initiated by avalanching on Oversteepened scoria slopes during eruptions. One small scoria pit on the lower southeastern slope operates intermittently with small production. | |

State: | This is one of the largest eruption points in the Central Highlands of Victoria. It is an excellent example of a complex eruption point with lava flows and scoria and a very clear example of a parasitic cone. The open spatter vent is a rare feature of eruption points in Victoria. It is a major site for collection of large, high temperature megacrysts of augite. This site is one of the most eroded of the scoria cones of the Newer Volcanics Province and shows the classical mode of early radial dissection predicted for such cones. The site has considerable potential for field teaching in geology. | |
Class 2: | Some of the significant features could be easily damaged by roadworks e.g. the lava outcrops, spatter vent and parasitic cone. Any extension of scoria quarrying should be planned in accordance with the geological significance of the site. | |
