Brief explanations for the table

Section R0–R1. In the lower part of the couloir, the main slope is covered with dense snow; in the upper part, it's a snow-covered ice slope. The snow holds well; insurance is provided through an ice axe.

Section R1–R2. The first bastion is traversed along an icy, snow-covered ledge; insurance is provided through pitons; climbing is of medium difficulty.

Sections R2–R3, R3–R4:

• Upwards to the right, a steep, icy slab with a gap in the middle
• Climbing is very difficult, relying on friction (there are very few holds)
• Insurance is provided through pitons; there are few cracks for piton placement

Section R4–R5. A system of main snow-covered and icy ledges and "ram's foreheads." Movement is straight up towards the base of a destroyed counterfort (start of the second bastion).

Section R5–R6. Up the right part of the counterfort directly under the yellow wall of the second bastion, along steep, destroyed rocks and a cleft. Climbing is difficult; in the middle part of the counterfort, on a small platform, is the I control point.

Section R6–R7. Monolithic sections of the wall are interspersed with "tiled" rock formations. The section is traversed:

• initially upwards to the right,
• then upwards to the left,
• further upwards to the right, towards a vaguely defined ridge that borders a large couloir.

Climbing is very difficult; insurance is substantial and continuous. At the top of the second bastion, organization of an overnight stay is possible.

Sections R7–R8, 8–9. Along snow-covered main ledges and "ram's foreheads" straight up towards the base of the third bastion (a grey wall with characteristic black streaks). The winding wall of the bastion is bypassed on the right through

a snow-ice couloir via a small rock island. In the dense firn, steps are well-formed. Insurance is provided through rock and ice pitons.

Section R9–R10. A steep chimney filled with flow ice. Climbing is very
