The Bungle Bungles Range is one of the highlights of the trip so far. It has presented a problem – how to refrain from adding 350 photographs to the blog !! It was a challenging drive into the Range involving over 250 Kms of rough tracks with many creek and river crossings. But it was more than worth it.
The Bungle Bungle Range is the landform that is the major component of the Purnululu National Park in Western Australia.
The distinctive beehive-shaped towers are made up of sandstones and conglomerates (rocks composed mainly of pebbles and boulders and cemented together by finer material). These sedimentary formations were deposited into the Ord Basin 375 to 350 million years ago, when active faults were altering the landscape. The combined effects of wind from the Tanami Desert and rainfall over millions of years shaped the domes. Weathering also helped create this marvel. Water seeps into the rock, and at night it expands as it gets colder. This creates small cracks which eventually wears out the rocks.
A 7 km diameter circular topographic feature is clearly visible on satellite images of the Bungle Bungle Range (Google Maps image). It is believed that this feature is the eroded remnant of a very ancient meteorite impact crater and is known as the Piccaninny impact structure.
