The pound is not the notorious wolfe creek crater. It’s the real thing, and we wanted to make it as real as we possibly could.

What is pound landform?
One of south australia’s most significant and distinctive geological landforms is the wilpena pound geological landform. It is an outstanding example of a remnant synclinal basin, formed as part of the N-S, NE- SW and E-W fold trends. The basin was formed during the last interglacial period, approximately 10,000 years ago, when the Earth’s surface was warmer and wetter than it is today.
The basin is located in the southern Kimberley region of Western Australia and is bounded on the north by the Nullarbor Plain to the west, and the Murray-Darling Basin and its tributaries, including the Wimmera River, the Murchison River and a number of smaller rivers, to its east.
This basin has been the subject of intensive study by geologists and geophysicists for more than a century, with the result that it has become a major focus of research in geophysics, hydrology, geomorphology, sedimentology and paleoclimatology.
What type of rocks are in the Flinders Ranges?
The Flinders Ranges (Figure 1) are made up of sedimentary rocks that were deposited during Neoproterozoic time in a sedimentary basin called the Adelaide Geosyncline. The basin was faulted 500 million years ago because of mountain ranges and plate movements. The faulting and folding of the rocks resulted in the formation of a series of troughs and canyons that are still visible today.

What formed Flinders Ranges?
The Flinders Ranges began forming about 800 million years ago, when an ancient sea deposited sediments in a basin known as the Adelaide Geosyncline. The basins were folded into mountains around 300 million years ago. The geology of the area has changed dramatically since the mountains were eroded away.
The new study, published today in the journal Nature Communications, shows that the flinders ranges were formed by a series of volcanic eruptions that occurred over a period of about 100,000 years.
This is the first time that geologists have been able to date the formation of these mountains using a technique called radiocarbon dating, which is used to determine the age of rocks by measuring the amount of uranium and thorium isotopes in them.
Is Wilpena Pound a desert?
Cradled by ancient mountain ranges on the edge of the desert, Wilpena Pound is the crowning jewel of the Flinders Ranges. The Adnyamathanha name of Ikara means meeting place and the Wilpena Pound has been a pilgrimage site for thousands of years.
In the early 1800s, it was the site of one of Australia’s first railway stations. Today, the area is home to a number of historic buildings, including the Royal Adelaide Hospital, which was built in the 1880s and is still used as a hospital today.
Is Wilpena Pound a crater?
Wilpena pound is a crater-like formation in the heart of the flinders ranges that covers more than 80sq km and is 1171m wide. It is the largest crater in South Australia and the second largest in Australia after the Great Dividing Range in Western Australia.
Pound was formed by the impact of a large meteorite that hit the Earth’s surface at a distance of about 1,000km. The impact was so powerful that it created a shock wave that spread out over a wide area and created the crater.
How was Wilpena Pound formation geological?
Superficially, Wilpena Pound resembles the remnant of an ancient and violent cataclysm, a massive meteorite crater or catastrophic volcanic eruption. The geological reality is not all that simple. The formation known as the K-Pg boundary was formed around 800 million years ago. This layer of sedimentary rock was deposited by a series of volcanic eruptions, some of which are still active today.
Pound is one of the oldest rocks in the world, dating back to the time when dinosaurs roamed the earth.
It is also the only rock that has been found to contain traces of life, including bacteria, archaea, fungi, and protozoa, as well as a variety of trace elements such as calcium, magnesium, potassium, sodium, zinc, iron, manganese, chromium, copper, nickel, cobalt, beryllium and selenium.
In addition, it contains trace amounts of carbon, hydrogen, oxygen, nitrogen, sulfur, phosphorus, silicon, aluminum, calcium carbonate, carbon dioxide, methane, ethane, ammonia, nitrous oxide and hydrogen sulfide.
