Geographic Overview

The peak of A. Grin (6525 m) is located in the Yazgulemsky ridge of the Central Pamir in the upper reaches of the Fedchenko Glacier, northeast of Peak Revolyutsii. Fairly gentle ridges descend from the peak:

• to Peak Revolyutsii
• to Peak Omar Khayyam To the northwest, towards the Fedchenko Glacier, a nearly sheer wall drops 1200 m, while to the southeast, towards the Grum-Grжимайло Glacier, very steep icy slopes descend. The area is characterized by a harsh climate, large temperature fluctuations, significant snowfall, and unstable weather. The upper reaches of the Fedchenko Glacier are difficult to access. Shuttle services typically begin from the tongue of the Abdukagor Glacier and take about two weeks. Prior to reaching the Abdukagor Pass (5070 m), all cargo was carried in backpacks. After the pass, sleds were used, which were prepared in advance in Togliatti.
