David Ridgers, Sand Dune Shape and Texture (LANDSCAPE 2024)

Two photos are from what is probably Tasmania's largest sand dune at curiously named Sea Devil Rivulet on the West Coast. The other two are from a much larger dune system in the Western Sahara in Morocco. Despite their geographic separation, the similarities in terms of shape and texture are apparent.
