Caving – also known as spelunking in the United States and Canada and potholing in the United Kingdom and Ireland – is the recreational pastime of exploring wild cave systems. In contrast, speleology is the scientific study of caves and the cave environment.
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word cave can also refer to much smaller openings such as sea caves, rock shelters, and grottos, though strictly speaking a cave is exogene, meaning it is deeper than its opening is wide, and a rock shelter is endogene.
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground.
Lascaux is a complex of caves near the village of Montignac, in the department of Dordogne in southwestern France. Over 600 parietal wall paintings cover the interior walls and ceilings of the cave. The paintings represent primarily large animals, typical local contemporary fauna that correspond with the fossil record of the Upper Paleolithic in the area. They are the combined effort of many generations and, with continued debate, the age of the paintings is now usually estimated at around 17,000 years. Lascaux was inducted into the UNESCO World Heritage Sites list in 1979, as an element of the Prehistoric Sites and Decorated Caves of the Vézère Valley.
Speleology is the scientific study of caves and other karst features, as well as their make-up, structure, physical properties, history, life forms, and the processes by which they form (speleogenesis) and change over time (speleomorphology). The term speleology is also sometimes applied to the recreational activity of exploring caves, but this is more properly known as caving, potholing, or spelunking. Speleology and caving are often connected, as the physical skills required for in situ study are the same.
The Cave of Altamira is a cave complex, located near the historic town of Santillana del Mar in Cantabria, Spain. It is renowned for prehistoric parietal cave art featuring charcoal drawings and polychrome paintings of contemporary local fauna and human hands. The earliest paintings were applied during the Upper Paleolithic, around 36,000 years ago. The site was discovered in 1868 by Modesto Cubillas and subsequently studied by Marcelino Sanz de Sautuola.
A cenote is a natural pit, or sinkhole, resulting from the collapse of limestone bedrock that exposes groundwater. The regional term is specifically associated with the Yucatán Peninsula of Mexico, where cenotes were commonly used for water supplies by the ancient Maya, and occasionally for sacrificial offerings. The term derives from a word used by the lowland Yucatec Maya—tsʼonot—to refer to any location with accessible groundwater.
The Cave of the Trois-Frères is a cave in southwestern France famous for its cave paintings. It is located in Montesquieu-Avantès, in the Ariège département. The cave is named for the three sons of Comte Bégouen who discovered it in 1914. The drawings of the cave were made famous in the publications of the Abbé Henri Breuil. The cave art appears to date to approximately 13,000 BC.
The Pomier Caves are a series of 55 caves located north of San Cristobal in the south of the Dominican Republic. They contain the largest collection of rock art in the Caribbean created since 2,000 years ago primarily by the Taíno people but also the Carib people and the Igneri, the pre-Columbian indigenous inhabitants of the Bahamas, Greater Antilles, and some of the Lesser Antilles. These caves have been damaged by the uncontrolled mining of limestone nearby.
The Caves of Nerja are a series of caverns close to the town of Nerja in the Province of Málaga, Spain. Stretching for almost 5 kilometres (3.1 mi), the caverns are one of Spain's major tourist attractions. Concerts are regularly held in one of the chambers, which forms a natural amphitheatre.
Tosantos is a municipality and town located in the province of Burgos, Castile and León, Spain. According to the 2004 census (INE), the municipality has a population of 60 inhabitants. Tosantos is located on the Camino de Santiago de Compostela, a 1200-year-old pilgrimage route that runs through France and Northern Spain to the Spanish city of Santiago. The hamlet has a pilgrim hostel which is open from April through October and hosts up to 50 pilgrims a night.
St. Michael's Cave or Old St. Michael's Cave is the name given to a network of limestone caves located within the Upper Rock Nature Reserve in the British Overseas Territory of Gibraltar, at a height of over 300 metres (980 ft) above sea level. According to Alonso Hernández del Portillo, the first historian of Gibraltar, its name is derived from a similar grotto in Monte Gargano near the Sanctuary of Monte Sant'Angelo in Apulia, Italy, where the archangel Michael is said to have appeared.
The Cave of Niaux is located in the Niaux commune, Ariège département in south-western France as part of a wider geological system that includes the Sabart Cave and Lombrives Cave in the hill of Cap de la Lesse de Bialac. The Niaux cave's system is complex and has a combined length of more than 14 km (8.70 mi) of underground passages and chambers. An archaeological site with a documented history of Paleo-human presence, Niaux contains numerous distinct areas and galleries of carefully drawn and vivid wall paintings, executed in a black-outlined style typical of the classic Magdalenian period, between 17,000 and 11,000 years ago.
Huápoca is an archaeological site located 36 kilometers west of Ciudad Madera, in the Huápoca Canyon region, northwest of the Mexican state of Chihuahua.
Les Combarelles is a cave in Les Eyzies de Tayac, Dordogne, France, which was inhabited by Cro-Magnon people between approximately 13,000 to 11,000 years ago. Holding more than 600 prehistoric engravings of animals and symbols, the two galleries in the cave were crucial in the re-evaluation of the mental and technical capabilities of these prehistoric humans around the turn of the last century.
The Cueva de los Murciélagos is a cave system in the Sierras Subbéticas located about 4 km southeast of the town of Zuheros in the southern province of Córdoba in Spain. Although the caves were discovered in 1868, they were not studied until 1938. The caves host one of the largest bat colonies in Andalusia.
The caves of Arcy-sur-Cure are a series of caves located on the commune of Arcy-sur-Cure, Burgundy, France. Some of them contained archaeological artefacts, from the Mousterian to Gallo-Roman times.
The La Garma cave complex is a parietal art-bearing paleoanthropological cave system in Cantabria, Spain. It is located just north of the village of Omoño, part of the municipality of Ribamontán al Monte. The cave complex is noted for one of the best preserved floors from the Paleolithic containing more than 4,000 fossils and more than 500 graphical units. It is part of the Cave of Altamira and Paleolithic Cave Art of Northern Spain World Heritage Site.
Ojo Guareña is a karst complex located in the Cantabrian Mountains of Castile and Leon, Spain, declared a natural monument by the government of Castile and Leon in 1996. It is composed of over 90 kilometres (56 mi) of galleries and passages within an area of some 13,850 hectares. The limestone formation containing the system is approximately 100 metres (330 ft) thick and sits on a massive water-resistant layer of marl. The caves were formed in the limestone by erosion sometime within the Coniacian Age. Ojo Guareña was considered the greatest karst system of the Iberian Peninsula until 2009, when a significant length of new passages was discovered in the Mortillano system.
The Grotte de Gabillou also known as Grotte de las Agnelas is cave in France in which prehistoric ornaments stemming from the Paléolithitic period exist. It is situated in commune of Sourzac in the department of Dordogne, Nouvelle Aquitaine and is a private property. Its sediments are from the Maastrichtian era.
