To the European eye, the Karoo is an ancient landscape untouched by major climate change or gla-ciation and evolving through erosional processes since deposition of Jurassic rocks, uplift, and the break up of Gondwana about 180 million years ago (McCarthy and Rubidge 2005).This break up marked the end of ～300 million years of sedimentation, largely under arid conditions, and a ～2 million year episode of violent volcanic eruptions and the outpouring of basaltic lava covering virtually the whole of southern Africa. Since this time, the interior of South Africa has been dominated by erosion (McCarthy and Rubidge 2005).
