The path from the Bezengi alpine camp to the left-bank moraine of the Maly Ukyu glacier behind the Southern counterfort of the Ukyu peak summit see in description 3. Immediately behind the Southern counterfort of the Ukyu peak, [move] right to a large scree and, in its lower part, partially snowed couloir that is snow-ice in its upper part (rope up! the couloir is prone to rockfall). 60–70 m up the rocks on the right side of the couloir, then traverse the couloir left and 60–65 m up the rocks on the left side (beware of streams!). Above the couloir's mouth, from under the slabs, move to the right side of the couloir and exit to the North-West
