Dimensions beyond imagination

La Verna cave room has a diameter of 250 meters, a height of 194 meters, a surface-area of 4,3 hectares and a volume of 3.6 million cubic meters. This makes it the biggest cavity open to the public in the world.

In 2003 a standard 4 person hot-air balloon was flown in La Verna.

 

60 years ago … the discovery of an extraordinary site

Discovered on the 13th of August, 1953 by the cavers Théodor, Lépineux, Eppely, Letrône and Ballandreaux, the la Verna cave is part of the huge underground cave-system of la Pierre Saint-Martin. The exploration of this system continues to this day. So far a total of 439 kilometers of underground galleries has been mapped.

 

Geological curiosities

Besides its incredible dimensions, the cave offers an insight into the geological history of the area. Three terrains can be distinguished: the shale and limestone of the Paleozoic era (350 million years old) and the limestone of the Mesozoic era (80 million years old). The Hercynian discordance, clearly visible in la Verna, facilitates the understanding of the formation of the cave-room and the flow of the underground rivers. The water finds its way from the infiltration zones on the high limestone plateaus, at an altitude of 2000 meters, to the resurgences 1500 meters further down, in the valley of Saint-Engrâce.

 

A remarkable fauna            

In this mineral world lives a unique community of animals, adapted to the dark depths of the karst. They are small invertebrates, blind, and without pigmentation. The two most common species observed in La Verna are the Aphaenops loubensi and Aphaenops cabidochei. In order to survive, these insects need an atmosphere saturated with humidity. After fecundation, the female lays a single egg, out of which a small larva hatches. Contrary to insects on the surface, this larva immediately metamorphoses to an adult, without feeding. The biologist Michel Cabidoche studied these animals in the 60’s. Since the opening of la Verna to visitors, in 2010, a team of researchers of the French national museum of natural history, under the leadership of Professor Arnaud Faille, closely follows their evolution.

 

 HISTORY

·         1950-51 : discovery and exploration of the 320 meters deep chasm Lépineux, in the massif of La Pierre Saint Martin (at the time the deepest cave-pit ever descended).

·         13 august 1952 : death of caver Marcel Loubens during the explorations.

·         13 august 1953 : Georges Lépineux, Jimmy Théodor, Daniel Eppely, Michel Letrône and Georges Ballandraux, divided into two groups, discover cave-room La Verna. One group opens the way, the other follows, doing the topographical survey. They join in La Verna, where they inscribe their names. They had found what was at the time -and remained for many years- the world’s largest underground volume. They had also set a depth-record.

·         1956-60 :the French National Electricity Company (EDF) decides to construct a tunnel. The plan is to capture the underground river that runs through La Verna for the production of electricity. It takes 4 years to dig the tunnel. For technical reasons the project is abandoned. The tunnel provides a great shortcut for cavers, who continue their explorations.

·          2000 : a private company, the SHEM (Société Hydroélectrique du Midi) re-launches the hydro-electric power project.

·         January 2006 : work begins. An access-road is constructed and the tunnel is restored. A dam is build across the river where it enters la Verna, creating a small reservoir of 200 m3. Cliffs separate the dam and the tunnel. A bridge spanning the gap needs to be build. More than 3 km’s of pressure pipe are led across the bridge, out through the tunnel, down to the bottom of the valley, where a hydro-electric power-plant is built. The project is innovating and totally integrated into the landscape. Tight cooperation between the SHEM and the local authorities has led to the opening of la Verna to the public.

·         1st July 2010 :La Verna opens to the public.

A federal and united project which associates:

-          3 communes (Sainte-Engrâce, Arette and Aramits) represented by the SIVU La Verna

-          The French Federation of Caving, represented by the committee of the Atlantic Pyrenees

-          The ARSIP (International Caving Association for Research at the Pierre Saint-Martin)

-          The SHEM (Société Hydro-électrique du Midi) subsidiary of the GDF-SUEZ group

-          The ONF, the Agence Publique de Gestion Locale and Euskal Concept Bâtiment (project management)

 

Supported by :

-          the European Union

-          the French State

-          the Regional Council of Aquitaine

-          the General Council of the Atlantic Pyrenees

Kungur Ice Cave - An invitation

"Pearl" of Russia. The current 2018 became significant for Russia. Holding the FIFA World Cup positively influenced economy of many regions of our country. Eleven cities of the Russian Federation accepting athletes and fans from around the world. Majority of them want not only to visit football matches, but also to get acquainted with nearby sights. Doesn't stand aside, the mislaid in Perm Krai, small and cosy city Kungur and the well-known Kungur Ice cave. Located in 300 km from Yekaterinburg, the city Kungur joined the cities-participants of the World Cup. From it tourists go to the Ice cave, having brought so various geography in visits statistics. It is possible indefinitely to list the countries residents which visited for these days the kingdom of eternal winter: Mexico, Peru, Australia, Spain, Lebanon, Brazil, China, USA, India, Denmark, Netherlands, Portugal, France … Foreign tourists and citizens of Russia, having visited the Kungur ice cave, often can't express that delight which covers them after the excursion on the fantastic underground world. What is surprising and unique in the Kungur Ice cave? In what it is one and only? First, in variety of forms of ice which are presented in the cave in more than 100 kinds. Secondly, an availability of long-term ices, which age is several hundreds of years, in spite of the fact that the cave is on an insignificant elevation mark. Thirdly, the cave length, it takes the fifth place on extent among caves of a plaster karst. Fourthly, there are several long and volume grottoes, that isn't characteristic of plaster caves. Fifthly, exotic contrast, during the summer period, from a heat in + 30 degrees outside to the subzero temperature of underground halls. This list of factors which characterize fantastic space can be listed infinitely, but as the popular Russian wisdom says "A picture is worth a thousand words". Welcome to the Kungur Ice cave!!!
