Geographical location of the area, its features, remoteness with indication of distance and time of approach or drive from the nearest settlement to the base camp (BC) and from BC to the start of the route. Description of the approach is provided according to the scheme: city (village), gorge, glacier, pass, summit.
Summit DVS («Dalnevostochnykh Stroitelei»), 3755 m above sea level, is located between UPI and Burevestnik peaks. GPS: 50.05308, 87.69923 — south of Akturu peak and SW of Akturu alpine camp. In good weather, it is clearly visible from the Akturu river in the alpine camp. Located in the Altai Republic, Kosh-Agachsky district, North-Chuya ridge, Akturu gorge.
The Akturu alpine camp can be reached from Kurai village (826 km along the Chuya tract) by a high-clearance vehicle — 32 km. By van, it usually takes about 2 hours.
The distance from Akturu alpine camp to DVS summit is about 11 km. The following is a description of the winter approach to the route.
Follow the trail to Baranii Lby. From there, descend to the Akturu river and ascend to the moraine ramparts under the eastern slopes of Radiist peak. It's not worth turning left too much, let alone climbing the separate moraine hillock Tronova. Even in a low-snow period, the gorge can be unpleasantly deep here.
Move towards Khitsan (under the nunatak dividing the Pravy Bolshoi Akturu glacier) and walk along the glacier along Khitsan to its western extremity, where it abuts the main glacier. Here is a large depression, possibly sheltered from the wind, where a tent can be set up for a storm camp.
The first time, following colleagues' tracks, we covered this segment with gear in 4.5 hours. The second time without gear — in 3 hours 20 minutes. Colleagues with a bivouac and ascent gear walked for 6 hours in bad weather.
Having reached the glacier on the southern side of Khitsan and overcome ice crevasses in rope teams, move along the glacier between the western ridge of UPI and the northeastern ridge of DVS towards the start of the ascent to Jelo pass.
In our case, it was more convenient to pass the crevasses further left — closer to the slopes of UPI peak.
From Khitsan to the pass, it took about 3 hours. Currently, there are three routes to the summit.

3. Characteristics of the Team's Actions
3.1. Brief description of the route passage.
Accompanied by photo illustrations (at least 4). The distance from Akturu alpine camp to the summit is about 11 km. We draw your attention to the fact that the ascent was made in early November.
Route:
- Follow the trail to Baranii Lby.
- From there, descend to the Akturu river and ascend to the moraine ramparts under the eastern slopes of Radiist peak.
- It's not worth turning left too much, let alone climbing the separate moraine hillock Tronova.
- Move towards Khitsan (under the nunatak dividing the Pravy Bolshoi Akturu glacier).
- Walk along the glacier along Khitsan to its western extremity, where it abuts the main glacier.
- Here is a large depression, possibly sheltered from the wind, where a tent can be set up for a storm camp.
Time taken for the section:
- The first time, following colleagues' tracks, we covered this segment with gear in 4.5 hours.
- The second time without gear — in 3 hours 20 minutes.
- Colleagues with a bivouac and ascent gear walked for 6 hours in bad weather.
Even in a low-snow period, the gorge can be unpleasantly deep here.
Having reached the glacier on the southern side of Khitsan and overcome ice crevasses in rope teams, move along the glacier between the western ridge of UPI and the northeastern ridge of DVS towards the start of the ascent to Jelo pass.
In our case, it was more convenient to pass the crevasses further left — closer to the slopes of UPI peak.
From Khitsan to the pass, it took about 3 hours.
| Section № | Description | Photo number |
|---|---|---|
| R0–R1 | Key section. Ice covered with a thin layer of snow, 45–60° slope. Movement in rope teams and crampons, using ice tools, ice screw belay. The slope is wide, moved in independent rope teams in parallel. Be attentive and choose a place with the cleanest ice — high avalanche danger! At the start of the slope, a large bergschrund — be extremely cautious! | Photo #3–6 |
| R1–R2 | Rocky ridge, simple rocks; 30–40° slope, местами стенки up to 90°. Rocks are partially iced. Movement in rope teams — simultaneous. On walls — alternating. | Photo #7–11 |
| R2–R3 | Snow-ice slope ending in a cornice; up to 50° slope. Movement in rope teams and crampons — simultaneous. Under the cornice, the leader moved right and chopped so that falling parts flew past the group. | Photo #12–13 |

3.2. Photo of the team on the summit with the control landmark.
Control landmark not found. Made one ourselves.

3.3.1. Route safety assessment.
The route seemed fairly safe to us, but when ascending the Eastern ridge, one needs to be cautious of avalanche danger and choose a safe part of the icy slope, as it is very wide and allows for finding a clean section. When exiting to the summit, the leader needs to move left or right — depending on the situation — to avoid undermining the cornice on the group.
3.3.2. Communication options on the route.
Used Baofeng radios with RHD-771 antennas for communication with Akturu alpine camp. Without the antennas, communication in BC was intermittent. When both radios were equipped with extended antennas, communication became stable. Conducted communication sessions every 3 hours, starting at 9:00.
No cellular communication on the ridge or summit.
3.3.3. Recommendations for subsequent climbers.
Comfortable for a start to spend the night in the depression near Khitsan.
3.3.4. Detailed information about the descent from the summit, indicating landmarks.
There are three descent options:
- Via the ascent route. Convenient because Abalakov anchors can be made during the ascent. 4 rappel sections.
- To the west towards Burevestnik summit and further from Fiskulturnik pass. Inconvenient in winter due to unknown pass conditions and subsequent need to trailblaze on Pravy Akturu glacier and untangle crevasses around Khitsan.
- Via NE ridge and further — to the middle couloir to the south. Inconvenient in winter due to unknown snow conditions on the ridge. However, after completing 3B on DVS, we did just that. One 30 m rappel in the couloir to the south. Potentially avalanche-prone!
3.3.5. Conclusion on the preliminary route assessment compared to classified routes of the same category of difficulty in the team's climbing experience.
Average for the area 3A. Interesting due to the presence of combined terrain.
More complex and engaging:
- Kzyltash via the North slope of SW ridge 3A
- DVS via NE ridge 3B
Easier in the icy part than:
- Kzyltash via the icefall on NW slope 3B
But more labor-intensive due to:
- Remoteness from alpine camp
- Long ridge with rocks
Much easier than:
- Radiist East via the North slope of Western ridge 3A
Well, everything is ice/snow in the area. 3B is easier than this route (7×70 m ropes on steep ice…). Likely similar in labor intensity to Akturu summit via Eastern ridge from Akturu Levyy glacier 3A.
