Driving north towards Outback South Australia and Ilkara-Flinders Ranges National Park. The park’s mountains have been looming over the horizon for the last 100km, slowly revealing their shape and structure. At first a dark hued haze on the horizon before the orange folds and laminations of the rock were close enough to catch my attention, like I knew they would.
Within the park, the Ediacaran Golden Spike has been carefully placed here to mark a visible change in Earth geological epochs. The dramatic change in the colour of the strata from dark brown to a pale yellow is significant in ways an appreciate but am not expert.
