The MacDonnell Range we entered today is a freak of Australian geography in so much that it is the only mountain range in Australia that runs east west. All the other ranges run north south.
Approximately 850 million years ago a shallow sea covered the whole area. Then approximately 600 million years ago the range was formed from the flat land sliding vertically during land movement.
During heavy rainfalls, water carves the rock causing widespread erosion over the mountains, leaving amazing rock formations through the range. If the rock hadn’t been washed away over the years the MacDonnell range would be about as big as the Rocky Mountain range in Canada.
