The central Wheatbelt is crossed east to west by a long chain of vaguely interconnected salt lakes and claypans and ephemeral watercourses. In extremely wet years saline water flows all the way to the Avon River and thence to the sea, but mostly it just sits and evaporates. Collectively, the many different lakes and streambeds make up the great Salt River.
In the picture we see one of the innumerable small, anonymous streams which sometimes carry water towards the Salt River but more typically sit bone dry, baking in the searing Western Australian heat. It was a measured 46 degrees when I took this picture.
