Geology Of Cornwall
The geology of Cornwall, England, is dominated by its granite backbone, part of the Cornubian batholith, formed during the Variscan orogeny. Around this is an extensive metamorphic aureole (known locally as killas) formed in the mainly Devonian slates that make up most of the rest of the county. There is an area of sandstone and shale of Carboniferous age in the north east, and the Lizard peninsula is formed of a rare section of uplifted oceanic crust. Coasts Cornwall forms the tip of the south-west peninsula of the island Great Britain, and is therefore exposed to the full force of the prevailing winds that blow in from the Atlantic Ocean. The coastline is composed mainly of resistant rocks that give rise in many places to impressive cliffs. The north and south coasts have different characteristics. The north coast is more exposed and therefore has a wilder nature. The prosaically-named ''High Cliff'', between Boscastle and St Gennys, is the highest sheer-drop cliff i ...

Boscastle
Boscastle () is a village and fishing port on the north coast of Cornwall, England, in the civil parish of Forrabury and Minster (where the 2011 Census population was included) . It is south of Bude and northeast of Tintagel. The harbour is a natural inlet protected by two stone harbour walls built in 1584 by Sir Richard Grenville and is the only significant harbour for along the coast. The village extends up the valleys of the River Valency and River Jordan. Heavy rainfall on 16 August 2004 caused extensive damage to the village. Boscastle lies within the Cornwall National Landscape (formerly Cornwall Area of Outstanding Natural Beauty, or AONB). The South West Coast Path passes through the village. History Boscastle was first inhabited by the Bottreaux family around 1080, and the name of the village comes from Bottreaux Castle (pronounced "Botro"), a 12th-century motte-and-bailey fortress, of which few remains survive. The castle, built sometime between 1154 and 11 ...

St Austell
Saint Austell (, ; ) is a town in Cornwall, England, United Kingdom, south of Bodmin and west of the border with Devon. At the 2021 Census in the United Kingdom, census it had a population of 20,900. History St Austell was a village centred around the parish church, until the arrival of significant tin mining in the 18th century turned it into a town. St Austell is named after the 6th-century Cornish saint, St Austol, a disciple of St Mewan. In a Vatican manuscript there is a 10th-century list of Cornish parish saints. This includes Austoll, which means that the church and village existed at that time, shortly after 900. St Austell is not mentioned in Domesday Book (1086). However, A. L. Rowse, in his book ''St. Austell: Church, Town, and Parish'', cites records which show a church was dedicated on 9 October 1262 by Bishop Bronescombe, and other records show a church there in 1169, dedicated to "Sanctus Austolus". The current church dates from the 13th–14th centuries, and ...

Bodmin Moor
Bodmin Moor () is a granite moorland in north-eastern Cornwall, England, United Kingdom. It is in size, and dates from the Carboniferous period of geology, geological history. It includes Brown Willy, the highest point in Cornwall, and Rough Tor, a slightly lower peak. Many of Cornwall's rivers have their sources here. It has been inhabited since at least the Neolithic era, when early farmers started clearing trees and farming the land. They left their megalithic monuments, hut circles and cairns, and the Bronze Age culture that followed left further cairns, and more stone circles and stone rows. By medieval and modern times, nearly all the forest was gone and livestock rearing predominated. The name Bodmin Moor is relatively recent. An early mention is in the ''Royal Cornwall Gazette'' of 28 November 1812. The upland area was formerly known as Fowey Moor after the River Fowey, which rises within it. Geology Bodmin Moor is one of five granite plutons in Cornwall that make up pa ...

RoughTor
Rough Tor (), or Roughtor, is a tor on Bodmin Moor, Cornwall, England, United Kingdom. The site comprises the tor summit and logan stone, a Neolithic tor enclosure, many Bronze Age hut circles, and some contemporary monuments. Toponymy In the 19th century, the hill was known as ''Router,'' and even into the late 20th century, some locals used this pronunciation. Geography Rough Tor is approximately one mile northwest of Brown Willy, Cornwall's highest point, on Bodmin Moor. Its summit is 1313 ft (400m) above mean sea level, making it the second highest point in Cornwall. Both hills are in the civil parish of St Breward and near Camelford. The De Lank River rises nearby and flows between the two hills. Rough Tor and Little Rough Tor are twin summits of a prominent ridge of granite, though there are actually three tors at the site: Showery Tor (Also known as Flat Cap Ned), Little Rough Tor, and Rough Tor. Crowdy Reservoir and the Lowermoor Water Treatment Works are not fa ...

Wave-cut Platform
A wave-cut platform, shore platform, coastal bench, or wave-cut cliff is the narrow flat area often found at the base of a sea cliff or along the shoreline of a lake, bay, or sea that was created by erosion. Wave-cut platforms are often most obvious at low tide when they become visible as huge areas of flat rock. Sometimes the landward side of the platform is covered by sand, forming the beach, and then the platform can only be identified at low tides or when storms move the sand. __TOC__ Formation Wave-cut platforms form when destructive waves hit against the cliff face, causing an undercut between the high and low water marks, mainly as a result of abrasion, corrosion and hydraulic action, creating a wave-cut notch. This notch then enlarges into a cave. The waves undermine this portion until the roof of the cave cannot hold due to the pressure and freeze-thaw or biological weathering acting on it, and collapses, resulting in the cliff retreating landward. The base of the cave ...

Fowey
Fowey ( ; , meaning ''beech trees'') is a port town and civil parishes in England, civil parish at the mouth of the River Fowey in south Cornwall, England, United Kingdom. The town has been in existence since well before the Norman invasion, with the local church first established some time in the 7th century; the estuary of the River Fowey forms a natural harbour which enabled the town to become an important trading centre. Privateers also made use of the sheltered harbourage. The Lostwithiel and Fowey Railway brought China clay here for export. History Early history The Domesday Book survey at the end of the 11th century records manors at Penventinue and Trenant, and a priory was soon established nearby at Tywardreath. the prior granted a charter to people living in Fowey itself. This medieval town ran from a north gate near Boddinick Passage to a south gate at what is now Lostwithiel Street; the town extended a little way up the hillside and was bounded on the other side b ...

River Camel
The River Camel (, meaning ''crooked river'') is a river in Cornwall, England. It rises on the edge of Bodmin Moor and with its tributaries its catchment area covers much of North Cornwall. The river flows into the eastern Celtic Sea between Stepper Point and Pentire Point having covered about making it the second longest river wholly in Cornwall. The river is tidal upstream to Egloshayle and is popular for sailing, birdwatching and fishing. The name ''Camel'' comes from the Cornish language for 'the crooked one', a reference to its winding course. Historically the river was divided into three named stretches. Heyl (, meaning ''estuary'') was the name for the estuary up to Egloshayle, the River Allen (, meaning ''shining river'') was the stretch between Egloshayle and Trecarne, whilst the Camel was reserved for the stretch of river between its source and Trecarne.
