text: During the Cretaceous the seamount was about 2 kilometres (1.2 mi) higher than present, perhaps even reaching 2,000 metres (6,600 ft) height above sea level; presumably it was then eroded during the Paleocene when a wave of erosion took place in western Britain and stripped much of the volcanic centres of northwest Scotland.
