Tian Shan
 
The displayed 3D-Modell (2,5D-Modell) represents an extract from northwestern part of the mountain range of the Tian Shan - the Sailiskiy-Alatau. It has the following boundaries: in the east the Leftern Talgar-valey, in the west the right flank of the Osörnaja-valey, in the south along the mountain ridge, which also describes the borderline to Kirghizia, and in the north it is limited by the 2000 m isohypsis. Besides, the entire Northern Tian Shan moutain range stretches between 74° and 80° latitute and 43° longitute on approximately 300 km length in west-east direction. Mountain ranges and heights of the summits are huge. mf-7.29

GEOGRAPHICAL BACKGROUND
The Tian Shan
Heaven Mountains
 
The Sailiskiy-Alatau shows in its morphological construction distinctive features of a high mountain region. It's structure is to be lead back to cold-term glaciation stage, as well as continuing periglacial and glacial processes. Mainly glacier cirques are situated between 3000 and 4000 m height, deep U-shaped valleys are also characteristic. The recent glaciation with 591 glaciers (> 0,1 km²) in mean reaches 3500 m above sealevel and has a total surface of 907,9 km.
The Tuyuk-Su glacier is one of 10 glaciers on earth with long-term observation.
The Dimitrijewa glacier is the biggest in Sailiskiy-Alatau with a surface of 15,4 km².
Further long-term studies have been accomplished on periglacial issues e.g. rock glacier observations and data-sets of permafrost temperatures.

The mid-asien location also causes strong climatic differentiation. So, the northern Tian Shan is characterised by strong continental climate. High precipitation and intensive seismic activities lead to mountain- and rock-falls. Rainfall events (approximately 600 mm/a) on the north-slope cause mudflows. Further, mudflow-protecting structures retain e.g. the Bolshaya Almatinka Osera at 2511.8 m above sealevel. mf-7.29

GEOLOGICAL GENESIS
Part Of The
Indian-Eurasian
Collision Zone
 
The Tian Shan limited belongs to the system of the middle-asian high mountain regions and with it, it is to be assigned to the Indian-Eurasian collision-zone. The mountain ranges of the Tian Shan mainly arised of the variscian mountain-formation stage, as well as of alpidic folding stage, which stands in context to the formation of himalaya mountains. The Tian Shan as well as Alai, Kunlun- and Nan Shan of central asia and the mountain ranges of East Siberia, Altai and Sajan, consist of old sediments and metamorphic rocks, which already deformed more than 250 million years ago. Great granite-intrusions and a strong metamorphosis are characteristic for the whole Sailiskiy-Alatau and especially for the chosen area. Tectonic tension concentrates at the mountain-margins and lead regularly to earthquake. mf-7.29

HOLIDAYS vs EXPEDITION
 
The Sailiskiy-Alatau shows an unlimited number of worthwhile trekking-possibilities and summit- goals between 3000-4500m above sealevel. Only few are opened up. So, almost every tour has it's pionier spirit and expeditionary- character in thin populated middle-asia.
- most popular trekking-route leads through the chains of the Sailiskiy- and Kungeiy-Alatau to the warm Lake Issyk-Kul / Kyrgystan
- most popular place to go for almaty people is Lake "Osera" with summer water temperatures around 5°C (by the way: an old AUDI 100 also manages to go there even if streets are only displayed for 4x4 cars)
- in the shown area are thirteen summits above 4000, of which Pik Sowjetov (4317m) and other six summits above 4300m sealevel represent the most simpliest too climb mf-7.29

& Wikipedia
 
The Tian Shan (Chinese: ??; Pinyin: Ti?n Sh?n; celestial mountains), also spelled Tien Shan, is a mountain range located in Central Asia, to the north and west of the Taklamakan Desert in the border region of Kazakhstan, Kyrgyzstan and the Xinjiang Uighur Autonomous Region of western China. In the south it links up with the Pamir. The Tian Shan are a part of the Himalayan orogenic belt which was formed by the collision of the Indian and Eurasian plates in the Cenozoic . The highest peak in the Tian Shan is Pik Pobedy (Victory Peak) which, at 7,439 m or 24,408 ft, is also the highest point in Kyrgyzstan and is on the border of China. The Tian Shan's second highest peak, Khan Tengri (Lord of the Spirits), at 7,010 meters, straddles the Kazakhstan-Kyrgyzstan border. The Torugart Pass , 3,752 m or 12,310 ft high, is located at the border between Kyrgyzstan and China's Xinjiang province. The major rivers rising in the Tian Shan are the Syr Darya and the Tarim river. Part of the Tian Shan are the forested Alatau ranges inhabited by pastoral tribes speaking Turkic languages. wikipedia-7.29.05
