Mount Porndon (Mount Porndon)
Mount Porndon is a 278 m volcano located 13 kilometres southeast of Camperdown in western Victoria, Australia.
Mount Porndon is on private land. There is a fire tower on the summit as well as several radio communications facilities. It is a composite volcano of scoria resting on lava disc and tuff. The area around Mount Porndon is known as the stony rises. Early settlers used the abundance of rock to build extensive stone fences in the surrounding area.
Mount Porndon is the central higher part of a volcanic complex including lava flows, tuff deposits and scoria cones and craters. The site covers a broad area including the major elements of volcanic sequence. A number of basalt lava flows extend from Mount Porndon forming rough stony rises, some of which reach Lake Corangamite. The younger of these flows formed an irregular lava disc roughly 3 km in diameter with a distinct and almost continuous perimeter in places forming a rocky wall 10 to 15 meters high. The stony rise flows have been dated at 300,000 years.
Overlying the lava disc is a thin layer of tuff. The main hills and cones were built from scoria eruptions which succeeded the phreatomagmatic stage after groundwater had been depleted. Small lava flows from some vents beneath the scoria are the last eruptive activity. The central cone of Mount Porndon has a crater 15 m deep and open to the west.

The ancestors of Aboriginal Australians began arriving from south east Asia approximately 65,000 years ago, during the last ice age. Arriving by sea, they settled the continent and had formed approximately 250 distinct language groups by the time of European settlement, maintaining some of the longest known continuing artistic and religious traditions in the world. Australia's written history commenced with the European maritime exploration of Australia. The Dutch navigator Willem Janszoon was the first known European to reach Australia, in 1606. In 1770, the British explorer James Cook mapped and claimed the east coast of Australia for Great Britain, and the First Fleet of British ships arrived at Sydney in 1788 to establish the penal colony of New South Wales. The European population grew in subsequent decades, and by the end of the 1850s gold rush, most of the continent had been explored by European settlers and an additional five self-governing British colonies established. Democratic parliaments were gradually established through the 19th century, culminating with a vote for the federation of the six colonies and foundation of the Commonwealth of Australia on 1 January 1901. Australia has since maintained a stable liberal democratic political system and wealthy market economy.
