Take Anna Creek Station, a well known cattle station in South Australia, near Simpson Desert between Coober Pedy and Lake Eyre. This station covers nearly 24,000 square kilometers. By comparison, Israel is barely 21,000 square kilometers, and the biggest ranch in America is just over 3,300 square kilometers. In fact, there might be close to a hundred cattle stations in Australia that are bigger than the biggest American ranch.
The coastline of the southern Tasmania, in Australia, is composed of stunning rock columns that protrude up to 300 meters from the sea level. These rocks are what geologists call dolerites, with its distinct elongated shape and hexagonal columns.
Dolerites form when molten rocks pushed up from the deep underbelly of the earth cools quickly and crystallizes to form small visible crystals in the rock. When the rate of cooling is just right, the rocks shrink in volume, causing the creation of cracks. The cracks allow the rocks in the interior to cool, resulting in more cracks. At the end, you get a large block of rock with long vertical and symmetrical cracks creating five or six sided columns. The columns can be just a few … Read the rest
