description Chiltern Escarpment Overview
The Chiltern Escarpment is the steep, northwest-facing chalk scarp along the western side of the Chiltern Hills in southeast England. It formed where Cretaceous chalk rises from the London Basin, creating a ridge above the adjacent clay vales, while the gentler dip slope descends toward the southeast. The landscape includes beech and other woodland, chalk grassland, farmland, dry valleys, and springs, and much of it lies within the Chilterns National Landscape.

The escarpment developed from Cretaceous chalk rising from the London Basin. Erosion created a steep scarp slope on one side and a gentler dip slope descending into the hills.
Which direction does the Chiltern Escarpment face?
The main scarp faces northwest. This steep-facing side contrasts with the gentler dip slope on the opposite side of the Chiltern Hills.
