This gully parallel to Glass Gorge Rd near Blinman delineates two chapters of sedimentary deposition in the formation of the Flinders Ranges – the Bunyeroo Formation purple shale (right), and white-weathering calcareous Wonoka Formation (left).
An amazing overview of the formation of the Flinders Ranges can be found in our feature essay, Legacy of Time, by the Royal Geographical Society of South Australia.
