Description: 1.6 km. south-east of Elmscleugh, 8.0 km. south-south-east of Dunbar, East Lothian. Glacial delta built out by side stream (out of photograph on right), and subsequently eroded by the modern burn. The cliff of superficial unconsolidated deposits (centre) being eroded by the modern stream is part of a delta or alluvial fan built out by a stream coming from the right of the photograph. This delta was probably deposited just after the retreat of the ice when the land surface was bare and erosion more rapid. After the final retreat of the Devensian ice-sheet, c.10,000 years ago, the landscape was bare and tree-less. This lack of vegetation cover allowed tremendous erosion of the exposed rock and superficial deposits. Through time, as plant life gradually became established, the landscape was stabilized and erosion reduced.
