The second walk was an easy one. It started from the Arkaroola Village complex. It follows the Mawson Valley and returns along the Spriggina ridge. The walk is named after two geologists who had a long association with the northern Flinders Ranges — Douglas Mawson and Reg Sprig. Or more accurately, Spriggina refers to a fossil from the late Ediacaran period in what is now South Australia that was found by Sprig. It is the oldest fossil organism to be described with a “head”.
We walked along the Mawson Valley towards a large, pinkish granitic rock known as Sitting Bull. Why did Mawson in 1945 name this rock complex in the Vulkathunha-Gammon Ranges after an American Indian? Why didn’t he give it an Adnyamathanha name? They are the people who historically lived in and belong to these Ranges, not the American Indians who lived on another continent across the Pacific.
