Dust Devil

Also known as Willy Willies, Dust Devils are a common site around the Flinders Ranges. The Bureau of Meteorology define the phenomena as

A localised dust filled vortex similar in shape to a tornado but of much less strength. They differ from dust storms in that they are a more localised and short-lived event. They form due to intense heating at the surface causing a rapid upward movement of parcel of air. This displacement of the surface air causes an inward movement of surrounding air, creating the common spiral shape of the dust devil. Dust devils are generally small in size compared with tornadoes, being about 3-100m in diameter and up to 300m high. Wind speeds inside the vortex reach a maximum of 100km/hr.

Bristly Sea-heath

Also known as the Clustered Sea-heath, Frankenia serpyllifolia grows about 30cm in heavy clays and gibber plains, seen here flowering in October near Copley in the northern Flinders Ranges.

Ediacaran Golden Spike

The base of the Ediacaran Period is defined by a Global Stratotype Section and Point (GSSP) marked by the Golden Spike in the Trezona Formation in Brachina Gorge. The lower glacial formation attributed to Snowball Earth is overlaid by the Nuccaleena Formation – a carbonate formed in shallow warm waters – displaying a distinct shift in climate that gave rise to Ediacaran biota, preserved in the fossil record of the Flinders Ranges.
