The Ridgetop country is amazing. This is the oldest part of the Flinders Ranges, much of it is granite. But the Ridgetop also includes some even more ancient sedimentary rock that was laid down in an ancient sea nearly 1600 million years ago; almost a billion years before much of the rest of the Flinders Ranges was created from sediment collected in a 600 km trough, called the Adelaidian Rift Complex ( formerly known as The Adelaide Geosyncline ), which is represented at the surface as a series of hills, mountains and uplands from eastern Kangaroo Island to just south of Oodnadatta in the far north of South Australia.
