The Wave, situated in the Vermilion Cliffs Wilderness Area, is one of the most bizarre landscapes in the USA. It looks like a wave of sour cream stirred into pumpkin soup. But it is made of sandstone. Once this sand was deposited in an old desert, kitted together, and was covered and buried. But when the Colorado Plateau was uplifted it surfaced. Rare desert storms did the sculpting (foto Paul Smit).
