Glaciers in ridge of Köoluu-Too.

The nature of Kyrgyzstan mountains.

“What is that feeling when you're driving away from people and they recede on the plain till you see their specks dispersing? - it's the too-huge world vaulting us, and it's good-bye. But we lean forward to the next crazy venture beneath the skies” 

Jack Kerouac, «On the Road».

Sights of Terskey Ala-Too mountains.

To the southeast from the Terskey-Ala-Too ridge, separated from it by the longitudinal valley of the Köoluu river, the KöoluuToo ridge stretches. Its average height is 4700 meters above sea level, the highest point, 5203 meters above sea level.
The main watershed ridge differs from the surrounding mountains in its alpine appearance. The flatter northern slope is cut by transverse valleys 5-7 kilometers long. The dismemberment of the southern slope is more complex and deeper.
There are 147 glaciers on the Köoluu-Too ridge with a total area of ​​228.2 square kilometers. Of these, 52 glaciers on the northern slope 88.3 square kilometers, in the south - 95 glaciers with an area of ​​139.9 square kilometers.
In quantitative terms, hanging glaciers slightly prevail (58%), located on the slopes of the lateral spurs, but 78% of the glaciation area falls on the glaciers of the valleys. On the northern slope, the glaciers of the valleys occupying the upper reaches of the transverse spurs have extensive feeding areas.
The largest glacier with an area of ​​14.1 kilometers square is located in the upper right tributary of the Ashu-Tor river. It begins in a circus, which reaches 7 kilometers across. Between 1943 and 1956 the glacier was stationary, but by August 1964, its length increased by 250 meters, and the edges became convex and steep.
Many glaciers of the northern slope recede, but not as much as the glaciers of the southern slope. Small and medium glaciers are stationary. The largest glaciers of the southern slope of the Köoluu-Too ridge are confined to the headwaters and to the joints of the ridge with its spurs.
Snow transport from the western and northern slopes through the saddles on the ridge plays an important role in the nutrition of glaciers.
Aylam Glacier. The largest on the southern slope of the Köoluu-Too ridge is the complex Ailam valley glacier, 5.1 kilometers long, 15.3 square kilometers in the upper Terekty River. It consists of four ice flows merged with the ends.
Recently separated from him a large right tributary with an area of ​​8.9 kilometers square, but part of it is not connected with the Aylam glacier with a common moraine with buried ice. It is planned to separate another left tributary.
The ends of the valley glaciers on the northern slope of Köoluu-Too descend on average to an altitude of 3770 meters above sea level, on the southern - to an altitude of 3800 meters above sea level. The height of the firn line is 4,000 and 4,160 meters above sea level, respectively.
The total area of ​​glaciation of the Keoluu-Too ridge is over 250 square kilometers, over 150 glaciers.
