Pennine Chain

Pennine Chain, extensive range of hills, northern England, extending south from the Cheviot Hills on the southern border of Scotland to the Midland Plain of England. In the northwest, the Eden Valley separates the Pennine Chain from the region known as the Lake District. In the south, the chain is broken by the Aire River, which traverses it in a general northwestern to southeastern direction, forming the Aire Gap. The Pennine Chain covers parts of Northumberland; Cumbria; Durham; Lancashire; North, West, and South Yorkshire; Derbyshire; and Cheshire. The southern foothills extend into Nottinghamshire and Staffordshire. The highest point, Cross Fell, is 893 m (2,930 ft) above sea level.
