On the coast north of Perth is one of the most unusual landscapes in all Australia — the Pinnacles Desert. Out of the bare, yellow, shifting sands rise thousands of huge, limestone pillars. Massive and immobile in such a stark landscape, these grotesquely sculptured stone columns look as if they have stood for ages. What exactly are pinnacles? How did they form? What natural processes were able to create such spectacular structures: And what can they tell us about the evolution of the coastal scenery of this part of Australia? This beautifully illustrated book addresses all these questions in clear, concise language.
