How old is Carnarvon Gorge?

Answer 1

The last layers of rock present in Carnarvon Gorge are layers of basalt dated radiometrically to around 27 million years old. Since then water erosion and, to a lesser extent, wind erosion have worked to carve away monumental quantities of stone - creating the feature you are asking about in the process. Therefore, most reference material on the Gorge regards its age as roughly 27 million years.

Answer 2

Carnarvon Gorge in Queensland, Australia, is estimated to be around 300 million years old, formed by erosion that has taken place over millions of years. It is a significant natural and cultural heritage site with diverse landscapes and indigenous rock art.
