The rocks in the region are amongst the oldest rocks in the world at over 2.7 billion years old. A wonderful feeling of timelessness is often felt by visitors as they travel through this vast landscape. As you drive the Outback Pathways you will be struck by the amazing rock formations the area entails; rich red breakaway ranges and impressive granite boulders dot the vast fields of scrub land. One of the most prominent of the Murchison's ancient rocks is Greenstone which forms winding ranges and hills throughout the Gascoyne Murchison Region. Granite is the most abundant rock type and most of the granites in the area range in age from 2.6 billion to almost 3 billion years old.
