Dark Peak

The Dark Peak is the higher, wilder northern part of the Peak District in England, mainly in Derbyshire and South Yorkshire.

It gets its name because (in contrast to the White Peak), the underlying limestone is covered by a cap of Millstone Grit which means that in winter the soil is almost always saturated with water. The land is thus largely uninhabited moorland plateaux where almost any depression is filled with sphagnum bogs and black peat. The High Peak is an alternative name for the Dark Peak, but High Peak is also the name of an administrative district of Derbyshire which includes part of the White Peak.

The areas of Millstone Grit form an 'inverted horseshoe' around the lower uncapped limestone areas of the White Peak. Hence the Dark Peak is said to cover the higher Derbyshire Peaks north of the Hope Valley, as well as the Western Moors in the area of Buxton, and the Eastern Moors stretching south towards Matlock. The Dark Peak is one of 159 National Character Areas defined by Natural England; as defined by Natural England, the Dark Peak NCA covers 86,604 hectares (334 sq mi) and includes the northern block of hills approximately bounded by Marsden, Stocksbridge, Hathersage and Chapel-en-le-Frith, plus the eastern moors south to Matlock, but excludes the western moors south of Chapel (which it places in NCA 53, the South West Peak) and the area around Glossop (in NCA 54, Manchester Pennine Fringe).
