Marsden, Yorkshire Pennines & March Haigh Reservoir

The Pennines (/ˈpɛnaɪnz/), 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 of the Midlands to Northumberland in North East England. From the Tyne Gap in the north, the range extends south through the North Pennines, Yorkshire Dales, South Pennines, and Peak District to end near the valley of the River Trent. The Border Moors and Cheviot Hills, which lie beyond the Tyne Gap, are included in some definitions of the range.
