How big is Mt Augustus?
It is two and a half times the size of the more popular Uluru, often described as the world's largest rock, in the Red Centre of Australia.
Mt Augustus covers an area of some 4800 hectares.
The difference between Uluru and Mt Augustus is that Uluru is a rock monolith consisting of a single rock while Mt Augustus is a monocline formed by a geological linear, strata dip in one direction between horizontal layers on each side.
Uluru is thus the largest rock monolith in the world and of monoliths and monoclines, Mt Augustus is the world's largest.

The naming of Mt Augustus
Mt Augustus was named in honor of Sir Charles Gregory (1819-1905), brother of the explorer Francis Gregory who was the first to climb the mountain during an epic 107-day journey through the Gascoyne region of Western Australia.
The mountain is known as Burringurrah by the local Wadjari Aboriginal people.
