The Flinders Ranges consist of very old folded rocks. Wilpena Pound, within the Flinders Ranges, resembles an enclosure of nearly flat land surrounded by rocky peaks, with only one easy way out. It is now part of a national park, and there is a tourist resort just outside. I stayed in the campground there for three days. One of the highlights was a half-hour "scenic flight" over Wilpena Pound. Another was a drive through some of the gorges in the ranges.
