Volcanic Caves of Victoria (Overview)

Map of the Newer Volcanic Province of Victoria and South Australia.
Detail of the younger flows in the western part of the province: Mt. Napier (33 ka), Mt. Eccles (~27 ka) and Mt. Rouse (~400 ka).
Most of the caves in the region are found in the Mt Napier and Mt. Eccles flows.
The Byaduk Caves are a cluster of large and small tubes, occurring where the lava flows spreading out from Mt Napier enter the Harman Valley and follow it west for about 20 km.
