Dry valley
A dry valley may be developed on many kinds of permeable rock, such as limestone and chalk, or sandy terrains that do not regularly sustain surface water flow. Such valleys do not hold surface water because it sinks into the permeable bedrock.
There are many examples of chalk dry valleys along the North and South Downs in southern England. Notably the National Trust-owned Devil's Dyke near Brighton covers some 200 acres (0.81 km) of downland scarp, and includes the deepest dry valley in the world - created when melting water eroded the chalk downland to the permafrost layer after the last ice age. The three-quarter mile long curved dry valley is around 700 feet (210 m) in height and attracts tourists with its views of Sussex, Hampshire and Kent.
