- Sullukol via the right contre-fors of the North face (D. Sukhodolsky's route, cat.4A). The path from the "Adylsu" alpine camp (group of 4-5 people) along the Tyutyusu gorge to the initial bivouac on the saddle of the Northern spur of the Western ridge of Sullukol summit is described in route 184. From the initial bivouac (departure at 2-3 am), ascend the Severny Sullukol glacier up-left and, bypassing the glacier's icefall from the left, reach a small upper snow plateau of the glacier. From the plateau, bypass the large crevasses on the left and reach the snowy slopes on the left side of the right contre-fors of Sullukol's North face. Having overcome the bergschrund on a steep snowy slope cut by numerous ice gullies, ascend directly up to the left of the rock base of the right contre-fors of the wall. Then, ascend up-right via a snow-filled couloir onto the rocks of the contre-fors. From here, ascend directly up via moderately difficult rocks of the contre-fors to the 1st rock pitch. Via steep and difficult rocks of the smooth pitch, ascend directly up (pitched climbing!). Then, via moderately difficult rocks, reach the 2nd pitch. Via steep monolithic rocks of the wall with few holds, and then via the inner corner of the pitch (pitched climbing!), ascend to the platform at its top. There is a control cairn on the platform. Via a short snowy slope, reach the rocks of the long and narrow 3rd rock pitch of the contre-fors. Via steep and difficult rocks of the pitch (pitched climbing!), and then on its right side, ascend to its top. From the top of the 3rd pitch, via a steep ice-snow ridge (cornice!), reach the 4th rock pitch of the contre-fors. Via steep, heavily destroyed and snow-covered easy rocks of the pitch, with small sections of moderately difficult rocks (pitched climbing!), ascend to the Western ridge of the summit. From here, turn left and via easy and moderately difficult rocks, ascend to the summit of Sullukol. From the Severny Sullukol glacier, 12-14 hours. Overnight bivouac on the summit. Descent via the Western ridge (see route 184). Special equipment for 4 people: main rope - 2x40m, accessory cord - 2m, rock pitons - 10-12, ice pitons - 3-4, rock hammers - 2, carabiners - 10-12, headlamps - 4, crampons - 4 pairs, tent - 1. Possible bivouac locations - on ice ridges and on platforms.
