Description: The Quiraing and Prison Rock, Trotternish peninsula, Skye, Inverness-shire. Escarpment of Tertiary plateau lavas and the major landslip. In late Tertiary times the lava plateau was tilted slightly to the west and considerably broken up by faulting, as a result this eastern seaboard was thought to have been cliffs up to 2000 feet high. The lower part of the cliff would have been composed of Jurassic sediments and dolerite sills, whilst above stood the great thickness of lava flows. Such an arrangement obviously would have been unstable with the sediments tending to slide under the weight of the super-incumbent lavas, so forming the landslips. Identical conditions occur in the Cascade Mountains in northern Washington State.
