In the foreground of the scene, a layer of resistant rock caps a fin protruding from the plateau. These resistant layers prolong the life of the fin, protecting the soft limestone from the forces of erosion and delaying the formation of hoodoos. Once this resistant cap has been eroded, the fin will have a short life (geologically speaking) as a series of hoodoos, before being weathered completely into a pile of clay and sand that will soon be washed away.
