Gouffre Mirolda
Gouffre Mirolda is a karstic cave located in the :fr:Haut-Giffre, Haut-Giffre. mountain range, in the commune of Samoëns, Haute-Savoie, France. It is connected to the Lucien Bouclier cave system, and has a depth of . It is the List of deepest caves, sixth deepest cave in the world. Exploration The cave was discovered in 1971 by Marc Degrinis, a shepherd. In 1972, the AVEN group in Lyon widened the entrance, and explored to a depth of to an impenetrable meander. In 1976, an upper entrance, the VF3, at , was discovered by the Villefranche Caving Club (EESV) and explored as far as the base of the first shaft on a narrow slope. The Gouffre Mirolda (CD11) was reinvestigated in 1980 by SC Lyon. With the help of the GS Cavernicole and the SC du Chablais, a depth of was reached. In 1981, the river was explored down to . Reinforced by the SS Genève and the Thonon Tauping Club, fossil galleries and upstream tunnels enabled the network to reach a height difference of in 1988. The unbl ...

Samoëns
Samoëns (; Franco-Provençal, Arpitan: ''Samouens'') is an alpine Communes of France, commune on the France–Switzerland border, Swiss border in the Haute-Savoie Departments of France, department in the Auvergne-Rhône-Alpes Regions of France, region in Southeastern France. It was the principal commune for the Cantons of France, canton that bore its name until it was abolished in 2015. The town of Samoëns is located in the French Alps' Vallée du Giffre (Giffre Valley), just southwest of Champéry in Valais. Population Stonemasons Stone has long been a traditional feature of the Upper Giffre Valley which is dotted with limestone quarries (hardness coefficient, 13). To supplement their income from farming, the men in the region used to work stone. In 1659, there were so many ''frahans'' (the local name for stonecutters and masons) in Samoëns and their expertise was so well known that they set up a very famous brotherhood. It engaged in charity work, taking care of the sick an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gournier Cave
The Gournier Cave is located near Choranche in the Vercors Massif in south-eastern France. The entrance is at an altitude of at the base of a cliff on the Presles plateau. It is one of the exsurgences (points at which an underground stream reaches the surface if stream has no known surface headwaters) of the Coulmes massif, and the cave is considered by many speleologists to be the most beautiful underground river in the Alps. Exploration In 1899 Decombaz visited the entrance lake by boat. In 1947, a climb over the lake by Jean Deudon gave access to a fossil gallery, which was explored by a team including André Bourgin for nearly , when two access points were discovered to the underlying river. The same team were stopped by a waterfall in 1949. The latter was climbed in 1952 by Pierre Chevalier, and the river was followed to a large chamber. In the 1960s, the Spéléo Club de la Seine found the way on, but were eventually stopped by a sump at a height of +. March 1973, the ...

Gouffre Jean-Bernard
Gouffre Jean-Bernard or Réseau Jean Bernard, sometimes known simply as Jean Bernard, is the seventh deepest cave in the world, and the third deepest one in Europe. It is in the Alps in Samoëns, France. The first entrance to the cave was found by the French caving group Groupe Vulcain in 1963. More entrances have been found over the years since, and currently at least thirteen are known. The highest entrance, known as C37, is at above sea level.. The cave is named after Jean Dupont and Bernard Raffy, two Groupe Vulcain members who died in 1963 in an unrelated expedition in Goule de Foussoubie Cave. Exploration The first entrance, known as V4, was discovered in 1963 and exploration in that year took the cave to a depth of . Further explorations in the following year reached the main drain, or master cave, of the system at a depth of . This was further explored downstream in 1965 and 1966, reaching the base of a wet shaft, the Puits des Affreux, at . Explorations in 1968 reach ...

Spring (hydrology)
A spring is a natural exit point at which groundwater emerges from an aquifer and flows across the ground surface as surface water. It is a component of the hydrosphere, as well as a part of the water cycle. Springs have long been important for humans as a source of fresh water, especially in arid regions which have relatively little annual rainfall. Springs are driven out onto the surface by various natural forces, such as gravity and hydrostatic pressure. A spring produced by the emergence of geothermally heated groundwater is known as a hot spring. The yield of spring water varies widely from a volumetric flow rate of nearly zero to more than for the biggest springs. Formation Springs are formed when groundwater flows onto the surface. This typically happens when the water table reaches above the surface level, or if the terrain depresses sharply. Springs may also be formed as a result of karst topography, aquifers or volcanic activity. Springs have also been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strike And Dip
In geology, strike and dip is a measurement convention used to describe the plane orientation or Attitude (geometry), attitude of a Plane (geometry), planar Geology, geologic feature. A feature's strike is the azimuth of an imagined horizontal line across the plane, and its dip is the angle of inclination (or depression angle) measured downward from horizontal. They are used together to measure and document a structure's characteristics for study or for use on a geological map. A feature's orientation can also be represented by dip and dip direction, using the azimuth of the dip rather than the strike value. Linear features are similarly measured with trend and plunge, where "trend" is analogous to dip direction and "plunge" is the dip angle. Strike and dip are measured using a compass and a clinometer. A compass is used to measure the feature's strike by holding the compass horizontally against the feature. A clinometer measures the feature's dip by recording the inclination pe ...

Hauterivian
The Hauterivian is, in the geologic timescale, an age in the Early Cretaceous Epoch or a stage in the Lower Cretaceous Series. It spans the time between 132.6 ± 2 Ma and 125.77 (million years ago). The Hauterivian is preceded by the Valanginian and succeeded by the Barremian. Stratigraphic definitions The Hauterivian was introduced in scientific literature by Swiss geologist Eugène Renevier in 1873. It is named after the Swiss town of Hauterive at the shore of Lake Neuchâtel. The base of the Hauterivian is defined as the place in the stratigraphic column where the ammonite genus '' Acanthodiscus'' first appears. A reference profile for the base (a GSSP) was officially ratified by the International Union of Geological Sciences in December of 2019, and is placed in La Charce, France. The top of the Hauterivian (the base of the Barremian) is at the first appearance of ammonite species '' Spitidiscus hugii''. In the ammonite biostratigraphy of the Tethys domain, the ...

French Federation Of Speleology
The French Federation of Speleology (, FFS), is a French organisation that represents all persons practicing or studying caving and canyoning and promotes the study and conservation of caves. It was formed in 1963 by the amalgamation of two organisations, the (CNS), or National Committee of Speleology, and the (SSF), or Speleological Society of France. History Société de spéléologie (1895–1914) Founded by Édouard-Alfred Martel in 1895, the was the first organisation of its kind in Europe. Between 1895 and 1900 the society published a journal entitled ''Spelunca''. The society folded in 1914 at the start of World War I. Spéléo-club de France (1930–1936) After the First World War, French speleology was represented mainly by Norbert Casteret and Robert de Joly, who continued the interrupted work of Martel's . On 18 March 1930, an organisational meeting led to the creation of the , whose headquarters were set up at Montpellier, in the headquarters of the Department ...
