Mountain travel in Pamirs.
“I see how time slowly flows over the highest mountains, how it gets lost in the tangle of deep, rocky gorges. A caravan stretches along a narrow path over the vertical cliffs. Again and again you have to unpack the horses, put the packs on your back and, tying yourself with woolen lassos, climb the rocks hanging over the angry river, and then use the same lassos to drag the horses, frightened by the heights, trembling, scratched by sharp stones, through a dangerous place.”
"Travels in the Pamirs." Pavel Luknitsky. 1955.
Mountain travel in Pamirs.
Upper limit of Perevalny glacier is located at an altitude of 5489 (Edelstein Peak, end of glacier at an altitude of 3705 meters above sea level, is left, initial (southern) branch of Sugran glacier, located on northern slope of Peter Great ridge in Lakhsh region of Republic of Tajikistan.The area of glaciers is constantly changing at a rate of tenths of a percent, and sometimes even whole percentages per year; at the same time, it can both decrease and increase as a result of annual changes in solid precipitation and summer air temperatures.
The XXth century was marked by almost continuous warming, especially strong in the middle of the century. Atmospheric precipitation is known to be associated with changes in the general circulation of the atmosphere, and it did not show such a clear trend throughout the century.
In the upper reaches, the Sugran glacier receives the first large tributary from the upper reaches - the Perevalny glacier. This active, steep glacier is located in the northern spurs of the Peter the Great mountain range and belongs to the basin of the Sugran River, which, in turn, is a left tributary of the Muksu River.
This glacier connects with the Sugran glacier, pushes its flow to the right side and can be traced far downstream, bordered by median moraines. Over the past decade, this glacier has been actively advancing.
