Chilterns, Chalk and Limestone Mixed

Author(s): Jeremy Lake

The Chilterns rise to just over 900 feet and stretch from the Thames in Oxfordshire across Buckinghamshire and Hertfordshire to Bedfordshire. The hills are formed by an outcrop of chalk, overlain by clay with flints, and comprise a steep scarp slope south and east of Aylesbury and a gradual dip slope falling towards the Thames valley. The plateau is cut by a series of through valleys that divide it into roughly rectangular blocks, to create a varied mix of landscapes. Approximately half of the land (52%) within the Character Area falls within the Chilterns Area of Outstanding Natural Beauty (AONB). Of the Character Area, 85.1% is open countryside, of which 69.3% is cultivated, whilst 14.9% is urban.
