- Dolra Vostochnaya via North Ridge (combined route, R. Khazardzhe, 4A cat. diff., fig. 32, 42). From the initial bivouac on the Dolra glacier moraine (approx. 3000 m), cross the glacier (closed crevasses) and approach the left side of the base of the North Ridge of Dolra Vostochnaya peak. From the glacier, traverse the bergschrund and ascend the snowy slope to the rocks on the left side of the broad base of the North Ridge. From here, ascend 50–60 m up (loose rocks) moderate difficulty rocks of the ridge crest, then 140–160 m up-right on steep rocks and slabs of above-moderate difficulty. Then traverse left into a couloir, then 250–300 m up moderate difficulty rocks of the ridge crest on the left side of the North Ridge, with short above-moderate difficulty walls and corners, until reaching a 15–20-meter wall on the North Ridge. Overcome the wall directly via above-moderate difficulty rocks. Then ascend 400–450 m up steep rocks of the North Ridge with short difficult walls. Traverse the 100–120-meter snowy (cornices) North Ridge to reach the East Ridge. Here, turn right and ascend the straightforward East Ridge to the summit of Dolra Vostochnaya. From the glacier, 10–12 hours.
