Stair Hole is located just to the west of Lulworth Cove and is a fantastic place to see and learn firsthand exactly how erosion shapes the coast adn world around us. From the viewpoint, the classic stages of erosion can be deen which include formations such as caves, blow-holes, arches, stacks, and stumps. The seas erosive force is developing these formations before our eyes. The erosion has helped scientists study the rock formations and the underlying rocks to help build a better picture of the history of the Jurassic Coast. On either side of Stair Hole, it reveals how the sedimentary beds that used to be flat have now been lifted up, tilted and twisted to form them into some amazing patterns. There are information posts at the viewing point explaining exactly what is going on and what you can see.
From the sea, Stair Hole appears to be a series of arches and caves that have been carved into the Portland Limestone, cracks and joins have formed in the limestone that has been eroded and widened by the waters around them. When viewed from the land, the arches in the limestone are far more visible, the Purbeck Beds have been exposed to the waters erosive power and these rocks erode at a faster rate which is ultimately causing Stair Hole to widen and expand.
