Fotod Devil's Dyke, Sussex

Devils Dyke January 2012, autor Ben124.

The Devil's Dyke V-shaped dry valley is the result of solifluction and river erosion. More than fourteen thousand years ago, the area experienced an intensely cold climate (but not glacial conditions). Snowfields capped the South Downs. Permafrost conditions meant that the chalk was permanently frozen. In summer, the snowfields melted and saturated the top layer of soil, because the water could not permeate the frozen chalk underneath. Waterlogged material situated above the permafrost slid down the gradient, removing material by friction, exposing deeper layers of frozen chalk. When the Ice Age ended, the snowfields covering the South Downs melted, and rivers formed across Sussex. The Devil's Dyke valley was completed by one such river. Local folklore explains the valley as the work of the devil. The legend holds that the devil was digging a trench to allow the sea to flood the many churches in the Weald of Sussex. The digging disturbed an old woman who lit a candle, or angered a rooster causing it to crow, making the devil believe the morning was fast approaching. The devil then fled, leaving his trench unfinished. The last shovel of earth he threw over his shoulder fell into the sea, forming the Isle of Wight.
