Geography
[edit]
Derbyshire mostly consists of hilly terrain, with uplands to the north and centre of the county, and lowlands to the south and east. The southern foothills and uplands of the Pennines extend from the north of the Trent Valley and into the north of the county. The Peak District National Park covers the majority of this area and Kinder Scout is the county's highest point, at 636 m (2,087 ft). The terrain is relatively low-lying across the lower Dove Valley, from the Trent Valley and southwards, the far south of the Derwent Valley and near its eastern borders with Nottinghamshire and Leicestershire.
The main rivers in the county are the River Derwent and the River Dove which both join the River Trent in the south. The River Derwent is the longest river in the county, at 66 miles (106 km), and rises in the moorland of Bleaklow, flowing throughout the Peak District and county for the majority of its course. The River Dove rises in Axe Edge Moor and forms a boundary between Derbyshire and Staffordshire for most of its length. The county also contains Church Flatts Farm at Coton in the Elms, near Swadlincote, which is the furthest point from the sea in the UK.
Landscape character[edit]
The varied landscapes within Derbyshire have been formed mainly as a consequence of the underlying geology, but also by the way the land has been managed and shaped by human activity. The county contains 11 discrete landscape types, known as National Character Areas, which have been described in detail by Natural England and further refined, mapped and described by Derbyshire County Council and the Peak District National Park.
The 11 National Character Areas found within Derbyshire are:
Dark Peak
White Peak
South West Peak
Derbyshire Peak Fringe and Lower Derwent
Nottinghamshire, Derbyshire and Yorkshire Coalfield
Southern Magnesian Limestone
Needwood and South Derbyshire Claylands
Trent Valley Washlands
Melbourne Parklands
Leicestershire & South Derbyshire Coalfield
Mease/Sence Lowlands
Geology[edit]
Derbyshire's solid geology can be split into two very different halves. The oldest rocks occur in the northern, more upland half of the county, and are mostly of Carboniferous age, comprising limestones, gritstones, sandstones and shales. In its north-east corner to the east of Bolsover, there are also Magnesian Limestone rocks of Permian age. In contrast, the southern and more lowland half of Derbyshire contains much softer rocks, mainly mudstones and sandstones of Permo-Triassic age, which create gentler, more rolling landscapes with few rock outcrops. Across both regions can be found drift deposits of Quaternary age – mainly terrace and river gravel deposits and boulder clays. Landslip features are found on unstable layers of sandstones and shales, with Mam Tor and Alport Castles being the best-known. Cemented screes and tufa deposits occur very rarely in the limestone dales and rivers, whilst cave systems have been created naturally in the limestone since Pleistocene times. A recently discovered cave chamber near Castleton, named Titan, is the deepest shaft and biggest chamber of any cave in Britain.
The oldest rocks are Lower Carboniferous limestones of Dinantian age, which form the core of the White Peak within the Peak District National Park. Because northern Derbyshire is effectively an uplifted dome of rock layers that have subsequently eroded to expose older rocks in the centre of the Derbyshire Dome, these are encircled by progressively younger limestone rocks, until they in turn give way on three sides to Upper Carboniferous shales, gritstones and sandstones of Namurian age.

Younger still are the sandstones, shales and coal deposits found on the eastern flank of Derbyshire, forming the coal measures, which are of Westphalian age. All these rock layers disappear south of a line drawn between Ashbourne and Derby under layers of clays and sandstones (Mercia Mudstone Group and Sherwood Sandstones) of Permo-Triassic age. Small amounts of carboniferous limestones, gritstones and coal measures reappear in the far south of Derbyshire from Ticknall (limestone) to Swadlincote (coal measures).
Some areas of the White Peak exhibit contemporaneous basalt flows (e.g. Ravens Tor at Millers Dale), as well as subsequent dolerite sill intrusion at a much later stage (e.g. near Tideswell Dale), whilst mineralisation of the carboniferous limestone in a subsequent period created extensive lead and fluorite deposits which have formed a significant part of Derbyshire's economy, as did coal mining. Lead mining has been important here since Roman Times. The more recent river gravels of the Trent valley remain a significant extractive industry today in south Derbyshire, as does the mining of limestone rock in central and northern parts of the county. Coarse sandstones were once extensively quarried both for local building materials and for the production of gritstone grinding wheels for use in mills, and both former industries have left their mark on the Derbyshire landscape.

As well as the protections afforded to the Peak District area under national and local policies, there are several green belts within the county, aimed at preserving the landscape surrounding main urban areas. There are four such areas, the first three being portions of much larger green belts that extend outside the county and surround large conurbations:
