Tor (rock formation)

A tor, known by geomorphologists as either a castle koppie or kopje, is a large, free-standing rock outcrop that rises abruptly from the surrounding smooth and gentle slopes of a rounded hill summit or ridge crest. In the South West of England, the term is also used for the hills themselves – the high points of Dartmoor in Devon and Bodmin Moor in Cornwall; the word tor, meaning hill, is notable for being one of the few Celtic loanwords to be borrowed into vernacular English before the modern era – such borrowings are words of a geographic or topographical nature. Another such word is crag. Tors are landforms created by the weathering of rock. Tors are less than 5 meters high. Many hypotheses have been proposed to explain their origin and this remains a topic of discussion among geologists and geomorphologists, physical geographers, it is considered that tors were created by geomorphic processes that differed in type and duration according to regional and local differences in climate and rock types.

For example, the Dartmoor granite was emplaced around 280 million years ago, with the cover rocks eroded away soon afterwards, exposing it to chemical and physical weathering processes. Where joints are spaced, the large crystals in the granite disintegrate to form a sandy regolith known locally as growan; this is stripped off by solifluction or surface wash when not protected by vegetation, notably during prolonged cold phases during the Quaternary ice ages - periglaciation. Where joints happen to be unusually spaced, core blocks can survive and escape above the weathering surface, developing into tors; these can be monolithic, as at Haytor and Blackingstone Rock, but are more subdivided into stacks arranged in avenues. Each stack can comprise several tiers or pillows, which may become separated: rocking pillows are called logan stones; these stacks are vulnerable to frost action and collapse leaving trails of blocks down the slopes called clitter or clatter. Weathering has given rise to circular "rock basins" formed by the accumulation of water and repeated freezing and thawing.

An example is found at Kes Tor on Dartmoor. Dating of 28 tors on Dartmoor showed that most are young, less than 100,000 years old, with none over 200,000 years old, they emerged at the start of the last major ice age. By contrast, in the Scottish Cairngorms, the other classic granite tor concentration in Britain, the oldest tors dated are between 200 and 675,000 years old, with glacially-modified ones having dates of 100-150,000 years; this may reflect more arctic climate.

Year 462 was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Leo; the denomination 462 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
