caption_attribution_description: English: The Malvern Hills located in the English counties of Worcestershire and Herefordshire. The hills have been designated by the Countryside Agency as an Area of Outstanding Natural Beauty. The highest point is the Worcestershire Beacon at 425 metres (1,394 ft) above sea level. The range is a natural border between Worcestershire and Herefordshire.
context_page_description: A hill chain, sometimes also hill ridge, is an elongated line of hills that usually includes a succession of more or less prominent hilltops, domed summits or kuppen, hill ridges and saddles and which, together with its associated lateral ridges and branches, may form a complex topographic structure. It may occur within a hill range, within an area of low rolling hill country or on a plain. It may link two or more otherwise distinct hill ranges. The transition from a hill chain to a mountain chain is blurred and depends on regional definitions of a hill or mountain. For example, in the UK and Ireland a mountain must officially be 600 m or higher, whereas in North America mountains are often taken as being 1,000 ft high or more.
  The chain-like arrangement of hills in a chain is a consequence of their collective formation by mountain building forces or ice age earth movements. Hill chains generally have a uniform geological age, but may comprise several types of rock or sediment.
  Hill chains normally form a watershed. They are crossed by roads that often use a natural saddle in the terrain.
