Cryopediments, as distinct from cryoplanation terraces, occur in the Chalk landscapes of Southern England. They exist as extremely gentle concave slopes at the foot of the steeper south-west facing slopes of asymmetrical dry valleys. They are essentially slopes of transportation related to the parallel retreat of the upper steeper slope section under past cryogenic conditions. Their preservation in the dry valleys of the Chalk is thought to reflect the lack of present-day fluvial modification whereas, on other more impermeable lithologies, such forms would have been quickly destroyed.
