The four major caving areas of the United Kingdom are in North Yorkshire, South Wales, Derbyshire, and Mendips. Minor areas include Devon, North Wales, and Grampian. One of the oldest established clubs, Yorkshire Ramblers' Club, was founded in 1892. Probably the first cave diving explorations in the world took place in Wookey Hole Caves in the 1930s using standard diving dress. Due to the long and active history of caving, almost every entrance with surface access has been fully explored, so the majority of new discoveries take place underground after months and sometimes years of cave digging. Notable recent discoveries since 1995 include Titan, the largest shaft in Britain, and Ogof Draenen, the second longest cave in Britain. Many clubs run expeditions abroad, often to particular territories such as Matienzo or Picos. ==Information resources== Many clubs hold extensive libraries recording decades of exploration in terms of surveys and logbooks, as well as newsletters, reports and books detailing the history of cave explorations both within their nearby areas and abroad on expeditions. Other information is in the form of extensive personal archives that have been bequeathed to the community. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Caving in the United Kingdom」の詳細全文を読む スポンサード リンク
