V. Brief Explanation for the Table of Main Characteristics of the Ascent Route
Section R0–R1: 45 m wall. "Crimea" type rock. This and the following section are prone to rockfall.
Section R1–R2: 20 m wall. "Sheep's foreheads" on the right and left. Snow and ice in places.
Section R2–R3: traverse right-up along a poorly defined ledge with small holds to a snow patch, then right to an inner corner.
Section R3–R4: ice-filled inner corner. The corner ends with a ledge going to the right. Control cairn.
Section R4–R5: small 7 m wall. Difficult climbing with an exit to a small sloping ledge.
Section R5–R6: a "reddish" chimney with an overhanging left side begins from the ledge. The chimney leads to a ledge.
Section R6–R7: traverse along the ledge to the right for 10 m. Then up the wall, which leads into a chimney ending with a small ledge.
Section R7–R8: a 20 m wall begins from the ledge, approaching a wall with characteristic black streaks. Ends with a long transverse crack.
Section R8–R9: overhanging section. Climbed using bolt pitons.
Section R9–R10: the overhang ends. There are smoothed ledges.
