- Mazeri East via East Ridge (a combined route, I. Solodueva, cat. 5A, fig. 32, 40). From Okhotnichye Ploshchadki (point 258), cross Ushbinsky Glacier to the right (closed crevasses) and ascend its southeastern branch to Mazeri Pass, located between the wall of South Ushba and the first pinnacle of Mazeri East Ridge. From the glacier, bypassing the bergschrund on the right, ascend a steep snow-firn slope (falling rocks from Ushba walls) and steep moderate rocks to Mazeri Pass. For the ascent path to Mazeri Pass from Gulsky Glacier, see point 256.
From the pass, ascend easy rocks of the East Ridge to the first pinnacle (cairn). Bypass the second pinnacle on the left via crumbling ledges, then reach a notch. From the notch, ascend steep easy and moderate rocks of the East Ridge with a 3-4-meter difficult wall to the third pinnacle, from where a 25-30 m rappel descends to a col beneath the fourth pinnacle.
Overcome the fourth pinnacle, and then the fifth ("Tower") directly via easy and moderate snow-covered rocks of the East Ridge with a 30-40 m rappel to a col area (cornice).
Continue along the East Ridge:
- a small snow-covered seventh pinnacle (cornices);
- descend from the ridge to the left and traverse via crumbling rocks of moderate and above-moderate difficulty,
- crossing snowy-ice gullies,
- ascend a steep snowy slope to a snowy notch of the East Ridge of the seventh pinnacle with "Mazeri Gates".
From the notch:
- via ledges on the right or left side,
- then ascend a difficult wall (key section) to the East Ridge.
Further, along the snow-covered and rocky East Ridge of moderate difficulty and a difficult wall, approach the ascent to the seventh pinnacle's summit. Bypass "Mazeri Gates" and the seventh pinnacle's summit via narrow ledges on the right, exiting onto a platform on the Western shoulder of the seventh pinnacle. Bivouac. From the initial bivouac, 10-12 hours.
From the shoulder, descend steep moderate rocks of the East Ridge to a snowy col (cornice), from where ascend steep crumbling rocks of moderate difficulty to the eighth pinnacle. From it, a gentle 100-120 m descent via crumbling snow-covered rocks, then 100-120 m along a snow-covered col (cornices), followed by 80 m ascent via steep rocks of moderate difficulty. Having passed the ninth pinnacle, exit onto a platform at the end of its ridge on the western side. From the bivouac site, 4-5 hours.
From the platform, descend to a snowy notch (cornice). Further, along a long snow-covered rocky East Ridge with a 60-meter steep section of above-moderate difficulty, approach the summit ascent. From beneath the ascent, traverse via rocks on the left side to the southern ridge of the summit.
Here, turn right and ascend easy and moderate rocks of the 150-meter South Ridge to the summit of Mazari East. On the platforms of the Southeast Ridge beneath the summit, bivouac. From the previous bivouac, 8-10 hours.
