The Pennines , also known as the Pennine Chain or Pennine Hills, are a range of uplands mainly located in Northern England. Commonly described as the "backbone of England" because of its length and position, the range runs from Derbyshire and Staffordshire in the North Midlands to Northumberland in North East Engl near the Anglo-Scottish border. The range starts near the valley of the River Trent to the south and extends northwards across the Peak District, South Pennines, Yorkshire Dales, and North Pennines, ending at the Tyne Gap. Beyond the gap are the Border Moors and Cheviot Hills, which are included in some definitions of the range.
