The mountain range Andygen is fully formed by limestones of Carbon and Devon ages. These limestones represent the single fragmented massif of many tectonic rifts. Geographically this range is one of the spurs of the Turkestan range and belongs to the Pamir-Alay mountain system. It administratively belongs to Batken territory in the South of Kyrgyzstan.
The continental climate with hot summers and cold winters forms here certain karst conditions. Generally Andygen is one of the several poleokarst mountain ranges on the territory of Kyrgyzstan. The limestone mountain range is situated in latitudinal direction.
It is very important this range is located in the South- Fergan hydrotermomineral zone. Therefore hydrothermal influence forms the caves of hydrotermokarst genesis, besides forming the caves of classical genesis, due to the fluid solutes of last geological eras. There are many beautiful artificially opened caves in the region of mining villages Kadamjay and Hidarhan which belong to the same zone.
There are 5 well- known caves of classical genesis in Adygen, some of them have second crystal formations. The Andygens caves may attract reaserchers of hypogenous minerals. The karst region occupies the territory of low mountain and middle mountain climatic zone. The karst is widely developed and have many crates, grottos, wells and caves.
Some karst craters with the diameter 2-3 meters and depth 1 meter on the east side of the range were described by geologists. Some of these craters have the ends of narrow ponoras. This region isn’t explored well enough in connection with potholing. Last time the caves were discovered in 1975. Local people tell about these caves, which they are scared to visit. tell about these caves, which they are scared to visit. The stream of warm air blows from some caves.
Reconnaissance research conducted in 2017 has shown the logistics for limestone range is very simple. Any car can drive up to the foot of limestone massif, and next step of foot research can be conducted in search of other caves.
There are many grottos in some conyons, which belong to the zones of tectonic rifts. It is difficult to define the entrance with the real caves, because most of them have narrow openings. It connected with hydrothermal karst processes which were here earlier. Big halls can be found behind these narrow entrances, like it happened in some well-known reserved caves in the Southern Kyrgyzstan. Climatic conditions are not so contrast.
The average air temperature in summer is 30-35°c, winter is warm with the air temperature 10-15°c. You can final springs in some canyons and bases of slopes. Precipitations are absorbed immediately on the limestone massif by many cracks and ponoras. The average level of precipitations is about 100-200mm per year. Judging by many karst forms of the last geological ages, there was subtropical climate. All formed caves in Andygen are paleokarst. Nowadays vegetation cover is very scarce.
For the first time speleologists discovered Madygen canyons in 2017 as very perspective in speleologi. This canyon is located 60km to the north of mountain massif Adygen. That is why the logistics becomes more convenient. The way from Andygen to Madygen is going through unique geological park Sary-Too. Geologically these canyons were formed in limestones the of the carbon period. The vertical walls of Canyons have the height of 300-400 meters in some places, which make Canyons very narrow, where their width decreases to 1m. That’s why it causes the main problem to see entrances to the caves on high vertical canyon walls.
Because limestone massif has numerous cracks, meteoric water directly plumbs into calciferous rock mass. Through the bed of the main canyon a stream, which beginning are karst streams of the neighbor limestone massif Takta-Boz situated further south, flows for the whole year. In summer when the bed of canyon is filled with water it provides perfect conditions for the canyon. It takes ten ends of different length ropes from five to twenty meters to go through the whole length of canyon.
For this reason, vertical benching and hydric places make canyon difficult to traverse.
In 2017, during reconnaissance expedition on the western vertical rock wall of the calciferous massif was discovered huge enough ambitious entrance which got conventional name ‘Flying’. The entrance is assigned to the vertical split cutting the whole limestone rock mass.
The height of rocky mass above the entrance is about 100-150 meters. The height of cliff between the bottom of canyon and the entrance is about 150-200 meters. So, it should be needed special climbing equipment and professionalism to get access to this entrance.
Marginal canyons flowing into the main canyon are no less interesting and heavy. Ambitious entrances are located on different altitude which you can reach only with special equipment.
This karst region hadn’t been investigated by speleologists before. We think it might be developed huge enough cave under this ambitious entrance.
In the summer months it is a hot weather both in Andygen and Madygen. The air temperature reaches 35-40 C. In some regions pinching-out the karst streams poplar woods spread out which create ideal place for the base camp.
After getting the permission on conducting research expeditions from the State Environmental Protection agency and also the permission from local authorities, our fund is planning to start speleological investigation in these karst regions of calciferous mountain massifs like Andygen and canyon Madygen in 2018. The best alternative is when one expedition will work in two regions consequently.
Speleological expedition to Andygen and Madygen canyons has been planned June, July, August 2018 or 2019. Everyone interested speleologists can take part in this research.
For research in these regions options of both single company and international team is possible.
From the point of view of logistics and price the team should consist no less than of 8-10 people.
Goals and objectives;
1. Karst area assessment
2. Spelunking of caves known to local people
3. Search and investigation of new caves
4. Investigation of numerous entrances in canyons on different levels
5. Search and investigation of bedding caves on table land
