The southern border of the Inner Tien-Shan is the Kakshaal-Too Range, which extends from the southwest to the northeast for almost 600 kilometers. Within the limits of the Inner Tien Shan, the western part of the ridge enters the valley of the Sary-Jaz River in the east with the highest point - Dankov peak, 5982 meters above sea level.
The northern slope is located on the territory of Kyrgyzstan ridge, southern - on the territory of the People's Republic of China.On the northern slope of the Kakshaal-Too ridge, within the indicated limits, 616 glaciers
an area of ​​907.6 square kilometers. Valley glaciers prevail (36% of the number and 76% of the area). In second place are the glaciers of the slopes, in third are the glaciers of flat peaks. The westernmost part of the Kokshaal-Too ridge to the gorge of the Kakshaal River in the east is a vast plateau about 4300 meters above sea level, the rest of the ancient peneplen.
Here, as well as on the small ridges of Kokkiya and Sarybeles located to the north, there are 63 glaciers with a total area of ​​70.7 square kilometers, of which 28 are glaciers of flat peaks, their area is 54.1 square kilometers.
The rest are small valley and caravan glaciers. A section of the ridge with a length of about 70 km between the through valleys of the Kakshaal and Chon-Uzengu-Kuush rivers is the highest (average altitude 5700 meters above sea level.
In the center of this section, in the area of ​​Dankov peak, is located the Ak-Sai glaciation site - one of the largest in the Tien Shan. In total, there are 153 glaciers on this site with a total area of ​​443.4 square kilometers.
Glacier valleys predominate in number and area, with most of these glaciers and the largest of them are grouped in the central part. These are valley and complex valley glaciers, occupying the upper reaches of the meridional valleys and feeding from firn fields that stretch as a continuous strip along the axial part of the ridge, and from the gentle slopes of the lateral spurs.
The wide ends of large glaciers go into the foothills, descending to a height of 3800 - 4300 meters above sea level. The largest glaciers of this section are Komarova Glacier in the upper Kyzylunet River, Mushketov Glacier in the Ortotash River Basin, Nalivkin and Mullitsky Glaciers in the upper Aital River and others.
These are complex valley glaciers, merging from several streams with well-defined middle moraines. About 150 kilometers in the eastern section of the Kokshaal-Too ridge, 400 glaciers with a total area of ​​393.5 square kilometers in the Ak-Shyyrak river basin.
In the western, less high part of this section, the maximum height is 4880 meters above sea level, there are many small disconnected caravan and hanging glaciers. To the east, the height of the ridge increases to 5390 meters above sea level.
In the same direction, the size of glaciers increases and the area they occupy changes type of glaciation. Glaciers receive additional feeding by avalanches from the slopes, and the nutrition asymmetry is clearly expressed - from the western windward, more snow-covered slopes it much more than the leewards of the east.
The end parts of glaciers are covered with moraines. There are signs of degradation - fresh deposited moraines, patches of dead ice. Between the Terskey-Ala-Too ridge in the north and the Kokshaal-Too ridge in the south there are several latitudinal ranges that rise relatively low above vast expanses of syrts and intermontane basins.
These are the ridges of Jetim-Bel, Jetim, At-Bashy, Borkoldoy, Dzhangiger and others. In crest Alpine relief with ancient glacial forms — mostly occupied by modern glaciers — is developed in parts of these ranges.
Icing is dispersed. Glaciers are located in the higher parts of the ranges. mainly on the northern slopes. In terms of number, hanging glaciers prevail on these ridges (65%), but valley glaciers occupy a large area (about 70%).
There are 17 glaciers larger than 5 square kilometers, but in general glaciation is represented by small glaciers. The height of the firn line is from 3900 to 4400 meters above sea level. To the north of the Kokshaal-Too ridge, separated by Chatyrkel and Ak-Says syrty and longitudinal valleys of the Muyuryum and Chon-Uzengu-Kuush rivers, they stretch from the south-west to the north-east At-Bashy, Dzhangiger and Borkolda ridges, which are a watershed between the rivers of the Naryn and Tarim depressions.
Ridge of Borkolda. The most significant is the glaciation of the Borkolda ridge (average altitude 4300 meters above sea level, maximum 5170 meters above sea level) - 396 glaciers with a total area of ​​250.3 square kilometers.
The Borkolda Range is a complex, deeply dissected system of mountain ranges about 100 kilometers. Most of the glaciers are located on the northern slope in the basins. the left tributaries of the Naryn rivers - the Karakol, Chakyrkorum and Tuyuk-Chakyrkorum rivers.
On the At-Bashy ridge, the highest point, 4786 meters above sea level, 149 glaciers with an area of ​​106.2 kilometers square. The area of ​​glaciation is approximately equally divided between the northern and southern slopes, but small kar and hanging glaciers predominate on the north, and on the south, which gently slopes down to Chatyrkel and Ak-Say syrts, mostly valley glaciers ending at an altitude of 3900 - 4100 meters above sea level.
The largest glacier, with an area of ​​6.9 kilometers square, lies at the head of the Mustavas River. On the ridge Dzhangiger 164 glaciers with an area of ​​59.8 square kilometers. Glaciation is more intense in the eastern part of the ridge, whose height is 4500 - 4700 meters above sea level.
Hanging glaciers predominate. The largest glacier with a length of 4 km and an area of ​​4.5 square kilometers lies in the upper reaches of the Dzhaldzhir River. The average height of the ends of the glaciers is 4000 meters above sea level.
On the ridge Jetim-Bel, up to 4627 meters above sea level, 116 glaciers, their area is 71.5 square kilometers. Small, mostly hanging, glaciers located along the ridge mainly in its western and central parts and occupy cars and circuses Northern exposure.
On the northern slope there are more glaciers and they are larger. The average height of the ends of the glaciers is 3750 meters above sea level on the northern slope and 3900 meters above sea level on the southern.
On the ridge Jetim, altitude up to 4896 meters above sea level, 195 glaciers with a total area of ​​135.6 square kilometers. The degree of glaciation and the size of glaciers increase from west to east with increasing ridge height.
The glaciers of the northern slope are larger. On the Nura ridge, there are glaciers only on the northern slope - 29 glaciers with an area of ​​25.9 square kilometers. The ends of the glaciers descend to a height of 3740 - 3790 meters above sea level.
On the ridge Suyuk 51 glacier with an area of ​​38.5 square kilometers. On the northern slope, small valley glaciers descend to the surface of the Arabel syrts (3900 - 4000 meters above sea level), and on the south - hanging glaciers.
The largest is the Mitor Basin Glacier, with a length of 2.6 kilometers and an area of ​​3.8 square kilometers in the Taragai river basin. In the Naryn-Too mountains (average altitudes 3800 - 4300 meters above sea level, the highest point 4531 meters above sea level, 239 glaciers with an area of ​​69.4 square kilometers.
On the northern slope, 2/3 of the glaciation area of ​​the Naryn-Too mountains is concentrated. Small glaciers only one glacier is more than 2 square kilometers. The height of the ends of the glaciers is 3800 - 3900 meters above sea level.
Small glaciers, mostly kar and hanging, are also found in the western part of the Inner Tien Shan on the highest sections of the Kekirim-Too Mountains (17 glaciers with an area of ​​3.6 square kilometers, Jaman-Too (66 glaciers with an area of ​​19.8 square kilometers, Bai Biche -Too and Ak-Chetash (8 glaciers with an area of ​​4.3 kilometers square) and Kapkatas (10 glaciers with an area of ​​1.6 kilometers square) (Bondarev, Zabirov. 1964; Bakov. 1983).
The orography of this area (the area of ​​Victory Peak) is the highest and most inaccessible part of the Tien Shan. In the north of the Terskey-Ala-Too ridge, it is a watershed between the Sary-Jaz river basin and the rivers of the Balkhash Lake basin.
To the south of it are the latitudinal ranges of Sary-Jazz, Tengri-Tag, Engilchek-Too (Inylchek-tau), Kayyngdy-Katta and Postyshev. The southern boundary of the Central Tien Shan is the eastern part of the Kokshaal-Too ridge, which encircles the area under consideration at a distance of more 100 kilometers.
The average height of the crests of the latitudinal ranges of the Central Tien Shan is 4,500 - 4,700 meters above sea level, the ridges rise from west to east (the highest peaks are Pobeda peak, 7439 meters above sea level, Khan Tengri peak, 6995 meters above sea level, Peak Marble Wall, 6150 meters above sea level.
The northern slopes of the ranges are short and steep, the southern longer and flat. These ridges in the east are connected by a meridional ridge stretched from south to north with heights of more than 6000 meters above sea level, from which glaciers flow west, to Kyrgyzstan, and east, to the People's Republic of China.
The northwestern slope of the Kokshaal-Too ridge has about 1000 glaciers with a total area of ​​about 1,500 square kilometers. The northern slope of Kokshaal-Too carries on the northern and northwestern slope, the Engilchek-Too and Kaindy ranges, about 300 glaciers with a total area of ​​over 625 square kilometers.
