The base camp of climbers is set up at the forest boundary on the shore of a small lake in the Left circus under the plateau, separating the circuses of Borus and Pik Koshurnikova at an altitude of 1300 m (see diagram) six hours walk from the settlement of hydrobuilders of the Sayano-Shushenskaya HPP Cheremushki.

The overhanging rock wall (10 m, 93°) is bypassed on the left via ledges (section R1). Further movement is simultaneous, belay via protrusions (210 m). The second rock wall (6 m, 90°) is climbed in the right part with piton belay, no bypass (section R2). Further, with alternating belay via ice axe, sections of the ridge with snow cornices are overcome (section R3, 30 m). Section R3 ends with a gap in the ridge. Rappelling 7 m (R4). Further, with alternating belay along the ridge to the base of the vertical wall (section R5, 30 m). The wall (10 m, 70°) with protruding slabs is overcome with piton belay (section R6). Then the ridge widens, movement across broken rocks is simultaneous (60 m). A large inclined slab (30°, 10 m) is climbed in the center with the organization of a belay (section R8).
