Geography

The central ranges are of a different topographical nature to the rest of the Flinders, being composed of roughly flat-lying strata, creating a high plateau into which spectacular gorges have been cut, instead of the buckled and folded strata further south which lead to the ubiquitous cuestas of Wilpena Pound. The Gammons are dominated by "The Plateau" in the southwest, which is contiguous with and of much the same height as the Blue Range further northeast, culminating in Benbonyathe Hill (1064m), the highest point in the Flinders north of Wilpena. Other notable and interestingly-named summits on the largely flat range and plateau include Elephant Hill (with adjacent outliers North Tusk and South Tusk), Mount Changeweather, Four Winds Hill, and Prow Point. Of these "rounded hills" of the plateau, Warren Bonython writes that "at their edge the slope, which was gentle near the crest, progressively steepens and then changes dramatically into a precipice plunging down to a rock-strewn creek bed perhaps a thousand feet below" (p 125).Some of the most interesting features of the ranges are these deep gorges cut in the south-eastern side of the Blue Range: Bunyip Chasm, The Terraces, and Fern Chasm are all areas often visited by...
