Stair Hole, just to the west of Lulworth Cove, is a remarkable small cove with natural arches cut into steeply-dipping Portland and basal Purbeck limestones. Through these arches and a gap where one has collapsed, the sea enters to erode the softer parts of the Purbeck limestones and shales. Soft multi-coloured Wealden strata slump southwards towards the sea. The most remarkable feature of Stair Hole is seen in the eastern cliff. Here is a cross-section throught the Lulworth Crumple, where small folds in the Purbeck strata are present within the steep northern limb of the Purbeck Monocline.
Resolutions: 2560x1600, 2560x1024, 1920x1200, 1920x1080, 1680x1050, 1600x1200, 1440x900, 1400x1050, 1280x1024, 1280x960, 1280x800, 1280x720, 1024x768, 800x480, 480x272, 320x480, 320x240.
