The summit Obmanchivaya is located in the upper reaches of the Cherlytym-Gorkhon valley, Tunkinsky mountain range, Vostochnye Sayany, to the west of the Khubuta river valley, along which the trail leads to the Shumak mineral springs — a popular tourist route in our region. The nearest settlements:

  • Nilova Pustyn settlement;
  • Khoito-Gol village.

Tunkinsky district of the Republic of Buryatia (district center — Kyren settlement). From them, you need to move along the old highway to the Sukhoy Ruchey tourist center 5 km, then:

  • transportation by a high-passability vehicle up the highway 3 km;
  • or on foot to the Cherlytym-Gorkhon river.

From there, a good trail leads into the valley to the base camp 6 km.

The valley is a dead end, regularly visited by local herb and wild food gatherers, and has a very simple approach. It is possible to transport cargo to the base camp on horses along the trail.

The chosen line passes through a beautiful, standalone bastion of two towers, standing in a cascade, very similar to a tooth — which is why it got its name. The route thread is quite straight. The route features:

  • a great variety of relief;
  • a considerable number of monolithic blind cracks.

The approach to the route from the base camp takes 2 hours 30 minutes.

According to the team's assessment, the route corresponds to similar routes in Vostochnye Sayany of 5A category of difficulty.

3. Characteristics of the Team's Actions

3.1. The approach to the summit Obmanchivaya from the base camp takes 2 hours 30 minutes. Follow the trail upstream along the river, the trail goes alternately along the left and right banks, then ascend via a distinct steep couloir towards Zub (WARNING! MAY BE AVALANCHE-PRONE WITH HEAVY SNOWFALL), the beginning of the route passes to the right of the central rib, directly under a pronounced cascade of rusty cornices from above, along a unilateral internal corner.

Section #DescriptionPhoto #
R0–R1Along the unilateral internal corner, move up the smoothed slabs towards the corner, belay — friends, station on pitons.
R1–R2From the station, traverse left approximately 7–8 m to the base of the internal corner, then move up through two large blocks, transition to the wall, belay — on pitons, station under a small overhanging cornice on a sloping ledge on anchors and friends.Photo 1
R2–R3From the station, move up using AID or challenging free climbing through a series of cracks, pitons, skyhooks, small friends. Approach the first small rusty cornice, another landmark is the rough relief. From it, traverse 3 m. Station on a ledge with grass behind the bend on pitons.Photo 2
R3–R4From the station, move up using AID or challenging free climbing through a series of cracks and walls in the direction of a not very distinct internal corner, then traverse right 8 m along large-block relief. Be cautious of loose blocks. Station in a niche on a sloping grassy ledge, pitons, or on a large block to the left.Photo 3
R4–R5From the station, move up: 2 m up the smooth rocks on friction from the block, then traverse 1 m left into a small internal corner with a characteristic even crack. Continue moving, bypassing the large-block relief along sloping slabs, in the direction of the second bastion, then slightly left and up. Station on a ledge with grass on pitons.Photo 4
R5–R6From the station, move slightly left and then up along the characteristic resonant crack approximately 7 m (free climbing). At the end of the crack, traverse left onto the southern wall approximately 3 m and then up along a partly blind crack using AID to a large lying block on a ledge, representing a small cornice. Having passed it, take a little left, exit climbing into a niche under a large cornice, bypass the cornice on the left. Station to the right on a small ledge on friends in a monolithic crack.Photo 5, 6, 7
R6–R7Along the monolithic crack from the station, move up (the crack veers left, belay — on friends). Then move up along the large-block relief, exit onto a huge sloping ledge. From the ledge, move up along slabs, then exit onto the ridge of Zub. You will be faced with a large rusty gendarme. Station on anchors.Photo 8
R7–R8From the station, simultaneous movement in a rope team along slabs via the simplest route through a small internal corner from blocks and then, bypassing the gendarme on the left, exit onto the main ridge.Photo 9, 10, 11
R8–R9Along the ridge, walk to the summit.Photo 12
