The Forest of Bowland, also known as the Bowland Fells and formerly the Chase of Bowland, is an area of gritstone fells, deep valleys and peat moorland, mostly in north-east Lancashire, England, with a small part in North Yorkshire. It is a western outlier of the Pennines.

Bowland at its most general most often refers to:

Black Combe is a fell in the south-west corner of the Lake District National Park, England, just 4 miles (6.4 km) from the Irish Sea. It lies near the west coast of Cumbria in the borough of Copeland and more specifically, in the ancient district of Millom. It is 1,970 ft (600 m) high and stands in isolation, some 10 mi (16 km) away from any higher ground; this factor offers an excellent all-round panoramic view of land and sea, weather permitting.

<span class="mw-page-title-main">Millstone Grit</span>

Millstone Grit is the name given to any of a number of coarse-grained sandstones of Carboniferous age which occur in the British Isles. The name derives from its use in earlier times as a source of millstones for use principally in watermills. Geologists refer to the whole suite of rocks that encompass the individual limestone beds and the intervening mudstones as the Millstone Grit Group. The term Millstone Grit Series was formerly used to refer to the rocks now included within the Millstone Grit Group together with the underlying Edale Shale Group.

The South Pennines is a region of moorland and hill country in northern England lying towards the southern end of the Pennines. In the west it includes the Rossendale Valley and the West Pennine Moors. It is bounded by the Greater Manchester conurbation in the west and the Bowland Fells and Yorkshire Dales to the north. To the east it is fringed by the towns of West Yorkshire whilst to the south it is bounded by the Peak District. The rural South Pennine Moors constitutes both a Site of Special Scientific Interest and Special Area of Conservation.

Grindleton is a village and civil parish in the Ribble Valley district of the English county of Lancashire, formerly in the West Riding of Yorkshire. Its 3,700 acres sit within the Forest of Bowland. The population of the civil ward taken at the 2011 census was 772.

The Craven Fault System is the name applied by geologists to the group of crustal faults in the Pennines that form the southern edge of the Askrigg Block and which partly bounds the Craven Basin. Sections of the system's component faults which include the North, Middle and South Craven faults and the Feizor Fault are evident at the surface in the form of degraded faults scarps where Carboniferous Limestone abuts millstone grit. The fault system is approximately coincident with the southwestern edge of the Yorkshire Dales National Park and the northeastern edge of the Bowland Fells.

The Mercia Mudstone Group is an early Triassic lithostratigraphic group which is widespread in Britain, especially in the English Midlands – the name is derived from the ancient kingdom of Mercia which corresponds to that area. It is frequently encountered in older literature as the Keuper Marl or Keuper Marl Series.

Easington is a civil parish within the Ribble Valley district of Lancashire, England, with a population in 2001 of 52. The Census 2011 population details have been grouped with the parish of Slaidburn. Before 1974, it formed part of Bowland Rural District in the West Riding of Yorkshire. It covers just over 9000 acres.

Gisburn Forest is a civil parish in the Ribble Valley, in Lancashire, England. Mainly lying within the Forest of Bowland Area of Outstanding Natural Beauty, the parish includes the larger part of the village of Tosside and the hamlet of Grunsagill to the south. Historically, the parish lay within the West Riding of Yorkshire. It had a population of 151 at the 2011 Census.

<span class="mw-page-title-main">Sherwood Sandstone Group</span>

The Sherwood Sandstone Group is a Triassic lithostratigraphic group which is widespread in Britain, especially in the English Midlands. The name is derived from Sherwood Forest in Nottinghamshire which is underlain by rocks of this age. It has economic importance as the reservoir of the Morecambe Bay gas field, the second largest gas field in the UK.

The geology of Lancashire in northwest England consists in the main of Carboniferous age rocks but with Triassic sandstones and mudstones at or near the surface of the lowlands bordering the Irish Sea though these are largely obscured by Quaternary deposits.

<span class="mw-page-title-main">Dent Group</span>

The Dent Group is a group of Upper Ordovician sedimentary and volcanic rocks in north-west England. It is the lowermost part of the Windermere Supergroup, which was deposited in the foreland basin formed during the collision between Laurentia and Avalonia. It lies unconformably on the Borrowdale Volcanic Group. This unit was previously known as the Coniston Limestone Group or Coniston Limestone Formation and should not be confused with the significantly younger Coniston Group.

The Craven Group is a lithostratigraphical term referring to the succession of mudstone and limestone rock strata which occur in certain parts of northern and central England and northeast Wales in the United Kingdom within the Chadian to Yeadonian sub-Stages of the Carboniferous Period. Other lithologies including sandstones, siltstones and chert occur within the group. The Group is subdivided into numerous formations, some of which previously enjoyed group status. In stratigraphic order, these are:

The Trawden Limestone Group is a lithostratigraphical term referring to the succession of limestone rock strata which occur in parts of Lancashire and neighbouring Yorkshire, northern England in the United Kingdom laid down within the Chadian to Brigantian sub-Stages of the Carboniferous Period.

The Bowland Shale or Bowland Shale Formation is a Carboniferous geological formation of Asbian (Visean) to Yeadonian (Bashkirian) age. It is known from outcrop and subsurface borehole data in the north of England, the Isle of Man, parts of North Wales and the Midlands. It is an organic-rich shale which, according to the British Geological Survey, is the source rock where "oil and gas matured before migration to conventional fields in the East Midlands and the Irish Sea", for example, the Formby oil field. The Bowland Shale, together with other organic-rich Carboniferous shale units, is being considered for exploitation for shale gas.

The Craven Basin is a sedimentary basin in northern England, having the shape of a southerly-tilted graben which was active during the Carboniferous period. It is one of a series of such basins which developed across northern England in this period separating upstanding blocks which were typically underlain by buoyant granites. The basin trends roughly east–west and is bounded by the Lake District block to the northwest, the Askrigg Block to the northeast and the Central Lancashire High to the south. One distinct section of the basin is a half graben which contains over 3km thickness of late Devonian to Courceyan strata and is referred to as the Bowland Sub-basin. These basins resulted from the crust of the region being subjected to a north–south lateral tension regime which began in the late Devonian and lasted through until the Visean.

The geology of the Yorkshire Dales National Park in northern England largely consists of a sequence of sedimentary rocks of Ordovician to Permian age. The core area of the Yorkshire Dales is formed from a layer-cake of limestones, sandstones and mudstones laid down during the Carboniferous period. It is noted for its karst landscape which includes extensive areas of limestone pavement and large numbers of caves including Britain's longest cave network.

The geology of the Peak District National Park in England is dominated by a thick succession of faulted and folded sedimentary rocks of Carboniferous age. The Peak District is often divided into a southerly White Peak where Carboniferous Limestone outcrops and a northerly Dark Peak where the overlying succession of sandstones and mudstones dominate the landscape. The scarp and dip slope landscape which characterises the Dark Peak also extends along the eastern and western margins of the park. Although older rocks are present at depth, the oldest rocks which are to be found at the surface in the national park are dolomitic limestones of the Woo Dale Limestone Formation seen where Woo Dale enters Wye Dale east of Buxton.

The Grey Stone of Trough is an historic boundary marker in Bowland Forest High, in the Trough of Bowland, Lancashire, England. A Grade II listed structure, erected in 1897 and standing on Trough Road, it marks the line of the pre-1974 county boundary between Lancashire and the West Riding of Yorkshire. Historically, the Trough marked the westernmost boundary of the ancient Lordship of Bowland.
