Jen-Shan Alpine Region.

“Having climbed out of the glacier again onto its left moraine, I went down to the valley, which I reached at 2 o’clock in the afternoon, at an air temperature of +12.5° C. Here I engaged in the highly interesting collection of Tien Shan alpine plants from the pastures of Marco Polo sheep (Ovis polli) and reached the bivouac of my caravan by evening, where the air temperature at 7 o’clock in the evening was +7° C."

Jeep trip to Tossor Gorge.

Tossor glacier group is located on northern slope of Terskey Ala-Too ridge, in upper reaches of gorge of  same name, on northern slope of Tossor pass, in Ton and Jety-Oguz districts of Issyk-Kul region. 
In the upper reaches of the Tossor River there are several small glaciers, the sources of which form the river of the same name with a length of 28.5 kilometers.
Tossor Central glacier group.
280 meters west of the Tossor pass there are glaciers that alternate one after another. In the cirque formed by the eastern and western spurs, on the northern slope, which departs from the main ridge of the Terskey Ala-Too ridge, there are 5 small glaciers.
The greatest length of one of them reaches 997 meters, the total width of the glaciers is 1377 meters. The total area of ​​glaciers is 1.19 square kilometers, the perimeter of the glaciers reaches 5.64 kilometers. The length of the moraine is 1.1 kilometers, the area of ​​the moraine is 0.47 square kilometers, the perimeter reaches 3.05 kilometers.
In the lower part of the glaciers, on the moraine there are two flowing lakes, one of them is clearly visible from the road that leads to the Tossor pass.

Tossor West Glacier.
To the west of the Tossor Central glacier group is the Tossor West glacier. The glacier is located on the northern slope of the Terskey Ala-Too ridge. The length of the glacier is 755 meters, the greatest width in the upper part is 630 meters.
