There are many theories how these vertical structures were created, one of them was that a forest of Moonah trees was smothered by a sand dune and water seeping through the sand creating a crust around decaying trunks, other theories appear more plausible due to the very dense arrangement of vertical trunk like structures. Today it is believed that the vertical structures are solution pipes, a result of chemicals, wind, rain, and seeping water.
Victoria is Australia's second smallest State and covers only 3% of Australia's land area but has the second highest population of all States and Territories. Victoria's mainland and islands have a total length of 2,512 kilometres coastline which is about 4.2% of Australia's 59,736 kilometres of coastline. Australia is the driest inhabited continent and Victoria is no exception although the state capital Melbourne has the reputation to have 4 seasons in one day. Victoria is located in the southeast of mainland Australia and includes the most southern point on mainland Australia at Wilsons Promontory National Park.
