Greenfield Valley

Greenfield Valley is a river valley through Saddleworth Moor in England's Peak District National Park. Historically this area of the South Pennines was part of Yorkshire but since 1974 it has been within the eastern edge of the county of Greater Manchester. The valley and the surrounding Saddleworth Moor are designated as 'Open Access' land for the public, following the Countryside and Rights of Way Act 2000. Much of Saddleworth Moor is a 9,000 year-old peat landscape of blanket bog. The upper Greenfield Valley is part of the Dark Peak SSSI (Site of Special Scientific Interest). The millstone grit moorland is typically covered with grasses, mosses, heather and bilberry and is habitat for mountain hares and moorland birds such as red grouse, lapwing, skylark, curlew, golden plover and meadow pipit. The RSPB operates Dove Stone Nature Reserve in the valley, which includes old quarry cliffs that are home to peregrine falcons. The Trinnacle is a dramatic large stack of three gritstone pillars at Raven Stones Brow. Since glaciers and ice sheets carved the cliff edge during the last Ice Age, weathering and frost-shattering of the rocks over thousands of years have formed the three-pronged Trinnacle outcrop. There are nearly 200 graded rock climbing routes on Ravenstones Crag. The valley's main stream Greenfield Brook is fed by Holme Clough and Birchen Clough. Greenfield Brook flows i
