Mam Tor

Mam Tor est une colline de 517 mètres située à proximité de Castleton dans le Peak District du Derbyshire, en Angleterre. Son nom signifie « colline mère », appelée ainsi en raison des fréquents glissements de terrain sur sa face orientale entraînant la formation d'une multitude de « mini-collines » en contrebas. Ces glissements de terrain, causés par des couches inférieures instables de schiste, offre le nom alternatif de Shivering Mountain (« Montagne frissonnante ») à la colline. En 1979, la bataille perpétuelle visant à maintenir la route A625 (Sheffield à Chapel-en-le-Frith) sur le côté est délabré de la colline est perdue lorsque la route est officiellement fermée en tant qu'axe de circulation, la section Fox House à Castleton étant redésignée A6187. La colline est couronnée d'une fortification à rempart unique datant de la fin de l'âge du bronze ainsi que du début de l'âge du fer, et de deux tumulus en forme de bol datant de l'âge du bronze. Au pied du Tor et à proximité se trouvent quatre grottes aménagées : Blue John Cavern, Speedwell Cavern, Peak Cavern et Treak Cliff Cavern, où l'on extrayait autrefois du plomb, du Blue John, du fluor et d'autres minéraux. Mam Tor est déclarée être l'une des sept merveilles du Pic par Thomas Hobbes dans De Mirabilibus Pecci paru en 1636.

Mam Tor is a 517 m (1,696 ft) hill near Castleton in the High Peak of Derbyshire, England. Its name means "mother hill", so called because frequent landslips on its eastern face have resulted in a multitude of "mini-hills" beneath it. These landslips, which are caused by unstable lower layers of shale, also give the hill its alternative name of Shivering Mountain. In 1979, the continual battle to maintain the A625 road (Sheffield to Chapel en le Frith) on the crumbling eastern side of the hill was lost when the road officially closed as a through-route, with the Fox House to Castleton section of the road being re-designated as the A6187. The hill is crowned by a late Bronze Age and early Iron Age univallate hill fort, and two Bronze Age bowl barrows. At the base of the Tor and nearby are four show caves: Blue John Cavern, Speedwell Cavern, Peak Cavern and Treak Cliff Cavern where lead, Blue John, fluorspar and other minerals were once mined. Mam Tor was declared to be one of the Seven Wonders of the Peak by Thomas Hobbes in his 1636 book De Mirabilibus Pecci.

Odin Mine

Odin Mine is a disused lead mine in the Peak District National Park, situated at grid reference SK133835. It lies on a site of 25 hectares near the village of Castleton, England. It is the oldest documented mine in Derbyshire and is thought to be one of the oldest lead mines in England. The mine is a Scheduled Ancient Monument and has biological and geological significance within the Castleton Site of Special Scientific Interest.

Blue John Cavern

The Blue John Cavern is one of the four show caves in Castleton, Derbyshire, England. The others are Peak Cavern, Treak Cliff Cavern and Speedwell Cavern.

Treak Cliff Cavern

Treak Cliff Cavern is a show cave near Castleton in Derbyshire, England. It is part of the Castleton Site of Special Scientific Interest and one of only two sites where the ornamental mineral Blue John is still excavated (the other is the nearby Blue John Cavern). As part of an agreement with English Nature, the Blue John that can be seen in the show cave is not mined but it is extracted in small quantities from other areas of the cave and made into saleable items like bowls, jewellery, and ornaments. The cave comprises three sections, the Old Series, discovered by lead miners in the 18th century, the New Series, discovered during blasting in the 1920s, and the New Series Extensions, discovered in 2014. Only the Old Series contains Blue John, but the New Series is well decorated with flowstone, stalagmites, and stalactites. The New Series Extensions are also highly decorated, but are only accessible by experienced cavers. Three human skeletons and flint implements from the Neolithic era were found in a small cave nearby in 1921.

Hollins Cross

Hollins Cross lies between Mam Tor and Lose Hill on the Great Ridge that separates Castleton and Edale in Derbyshire, England. Hollins Cross is the lowest point on the ridge and is therefore a popular route taken by walkers wishing either to cross from one side to the other, or to start a walk along the ridge. It was also the traditional route from Castleton to Edale. Coffins from Edale were taken over Hollins Cross to Hope church until a church was constructed in Edale, leading to the nickname of the "coffin road" for this route. There are three well-used paths on both sides of the ridge leading to Hollins Cross. The path west of Hollins Cross is a gentle climb on a paved path of around one kilometre to the summit of Mam Tor. The path east is slightly more taxing with the initial climb up Back Tor being unpaved and badly eroded. Beyond Back Tor the path continues on to Lose Hill on a paved surface. Hollins Cross is named for an actual cross that was raised here, but which had disappeared by 1905. A memorial to Tom Hyett (formerly surmounted by a topograph) was erected by the Long Eaton and District Group of the Ramblers Association in 1964.
