3. SPECIAL PROJECT - UNKNOWN KARST NARYN-TOO, June 2 - June 14. Dates are preliminary

Mountain range Naryn-Too (Middle Tien-Shan)

The Naryn-Too mountain range remained as one of the unknown karst areas until 2018. In September 2018, a British international expedition together with Kyrgyz speleologists discovered this area in the Middle Tien-Shan, almost in the center of Kyrgyzstan. According to British speleologists, the limestone from which the mountain range is built is a classic example for the formation of caves.

This mountain range is completely composed of carbonate limestone of the Carboniferous age (C), in which the content of calcite (CaCO3) is more than 70%. The range is positioned from east to west. Its length is about 80 km with a width of 15 km. The height of the watershed of the range is more than 3,700 meters above sea level, and the height above the surrounding valley is about 1,000 meters.

The southern and northern slopes of the range are carved with gorges and canyons. During the reconnaissance expedition, speleologists discovered several black openings in the canyons, almost everywhere there are signs of a karst landscape. During the British 2-day expedition, we made an investigation of the Char canyon at the western end of the range. The height of the canyon walls reaches 300-400 m.

Almost the whole year, springs are drained in the thalwegs of gorges and canyons, despite the fact that the snow cover lies on the plateau and the watershed of the range for only 3-4 months a year. The flow rate of the springs reaches 50 liters per second.

One of these karst springs is located at the western end of the mountain range. The source drains the limestone massif and forms a waterfall. In the fall, the water flow of the waterfall dries out, but its flow rate rises again in spring. In 2017, we researched the upper western part of the range, but did not reveal any concentrated catchment area. Therefore, the interior of the massif represents a hydrogeological system, which possibly forms karst galleries, where water flows can gather from a large area. In the area of the source, several holes were found that represent the mouth of the waterfall. Currently, the waterfall is a place of religious worship for the locals.

Locals told us that similar waterfalls with similar genesis are located on the northern slope of the range and its eastern extremity.

For work in the karst area, logistics is fairly simple. In order to explore the mountain range it is not necessarily the use a good off-road transport. We usually use a mini bus to deliver the base camp from Bishkek. From the base camp location, you can make radial exits for 2-3 days, using local horses to transport cargo. We plan to put the base camp in picturesque canyons, with springs of potable water, in the western tip of the range, as well as an alternative option in one of the gorges of the northern slope of the range.

The air temperature in May-August is about 28-30 degrees during the day and 20-22 degrees at night. From April to September there are frequent rains in the area. Sometimes rain may continue for 2-3 days.

This territory is reserved; therefore our Foundation gets the corresponding permission for researches. We invite all interested speleologists to participate in the study of the new karst region of Tien-Shan.

The purpose of the expedition:

- Search and research of new caves

- Biological research

- Geological research

Expedition dates can be changed. If the group is one - from one club, association, federation, then the group has the right to change the dates of the expedition. If the group is mixed, then we rely on our capabilities and the capabilities of the majority of potential participants. At the moment we have indicated the most favorable season of the year according to the climatic conditions in a particular geographical area.
