Gritstone or grit is a hard, coarse-grained, siliceous sandstone. This term is especially applied to such sandstones that are quarried for building material. British gritstone was used for millstones to mill flour, to grind wood into pulp for paper and for grindstones to sharpen blades. "Grit" is often applied to sandstones composed of angular sand grains. It may commonly contain small pebbles. [1]

"Millstone Grit" is an informal term for a succession of gritstones which are to be found in the Pennines (including the Peak District) of northern England. [2] These sediments were laid down in the late (upper) Paleozoic era, in the Carboniferous period, in deltaic conditions. The Millstone Grit Group is a formal stratigraphic term for this sequence of rocks.

The gritstone edges of the Peak District are an important climbing area and the rock is much relished by English climbers, among whom it has almost cult status and is often referred to as "God's own rock". [3] The rough surface provides outstanding friction, enabling climbers to stand on or grip the subtlest of features in the rock. (See the main article on rock climbing in the Peak District.)

Rock climbing is a popular activity in the Peak District; particularly on edges such as Stanage or Froggatt. Generally the climbing style is free climbing and the rock is either gritstone or limestone. Climbing has been practised in the Peak District since the late 19th century; James W. Puttrell is generally credited with starting the sport. The first climbing guidebook to the area was Some Gritstone Climbs, by John Laycock, published in 1913. There are over 10,000 routes in the Peak District. One of the most famous Peak District climbers, and a pioneer of many new routes, is Ron Fawcett. The climb known as "Master's Edge", on Millstone Edge, near Hathersage, is a testament to his skill and strength. The climb is graded E7 6c and rises 19m up the near vertical edge.

Stanage Edge, or simply Stanage is a gritstone escarpment in the Peak District, England, famous as a location for climbing. It lies a couple of miles to the north of Hathersage, and the northern part of the edge forms the border between the High Peak of Derbyshire and Sheffield in South Yorkshire. Its highest point is High Neb at 458 metres (1,503 ft) above sea level. Areas of Stanage were quarried in the past to produce grindstones, and some can still be seen on the hillside—carved, but never removed.

<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.

Stanton Moor is a small upland area in the Derbyshire Peak District of central northern England, lying between Matlock and Bakewell near the villages of Birchover and Stanton-in-Peak. It is known for its megaliths – particularly the Nine Ladies stone circle – and for its natural, wind-eroded sandstone pillars. The Peak District Boundary Walk runs across the moor.

<i>Hard Grit</i> 1998 British film

<span class="mw-page-title-main">South Pennines</span> Region of moorland and hills in northern England

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.

Roaches Grit is a coarse sandstone which outcrops widely throughout the western part of the Peak District of northern England and gives rise to several significant landscape features in the area. Its counterpart in the eastern part of the National Park is the Ashover Grit.

Ron Fawcett is a British rock climber and rock climbing author who is credited with pushing the technical standards of British rock climbing in traditional, sport, bouldering and free soloing disciplines, in the decade from the mid-1970s to the mid-1980s, and of pioneering the career of being a full-time professional rock climber. At the end of the 1970s to the early 1980s, Fawcett was widely considered the best and most notable rock climber in Britain.

Some Gritstone Climbs is a rock climbing guidebook written by British lawyer John Laycock (1887–1960). The book's subtitle, included uniquely on the frontispiece, is Some Shorter Climbs . It was published in Manchester in 1913 by the Refuge Printing Department. Although focusing on rock climbing in the Peak District, it covers several adjacent cliffs outside this region, and despite its title, referring to the Millstone Grit geology of many of the cliffs, it includes several cliffs consisting of other rock types, including mountain limestone and red sandstone.

Harthill Moor is a small upland area in the Derbyshire Peak District of central and northern England, lying between Matlock and Bakewell near the villages of Birchover and Elton. The moor is within the southern portion of Harthill civil parish. Its highest point is 272 metres (892 ft) above sea level. The River Bradford flows along the northern edge of the moor past Youlgreave and into the River Lathkill at Alport. Harthill Moor is a rich prehistoric landscape with several protected Scheduled Ancient Monuments.

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.
