Tactical Actions of the Team
We chose the route of A. Moshnikov 1984 for the ascent of Ak-su, as, in our opinion, it is "an ideal route for a winter ascent." According to the team's calculations, our winter ascent on the Ak-su wall was the fifth. The route is mixed, requiring constant transitions from one type of terrain to another, as well as confident possession of both rock and ice techniques in winter conditions. Our main task was:
- safe passage of this route in autonomous mode by three (the team was alone in the gorge, without assistance or rescue teams),
- in the shortest possible time,
- without processing and using bolt climbing techniques.
The tactical plan was:
- 5 days for the ascent and 2 days for the descent,
- food and fuel supply for 10 days,
- the team had 4 ropes and a platform for organizing overnight stays,
- working in any weather.
We started the route at 06:00 on February 6, after a three-day snowfall. On the first day, we covered 11 ropes with a starting load and organized an overnight stay at the end of the ice couloir on the border of rocks and ice. We also fixed 2 ropes above the overnight stay location, thus covering 13 ropes.
On the second day, we fixed 4 ropes on mixed terrain and moved the camp another 5 ropes higher.
On the third day, we passed the rocky part in the middle of the wall, as well as a traverse under "Moshnikov's chip"+, and moved the camp under the chip to the level of the "Cross".
On the fourth and fifth days, in snowfall conditions, the team fixed 4 ropes up the chip, passing the key section. The snowfall greatly complicated the work on the wall with constant powder snow avalanches, so the work took a day longer than planned.
At 05:00 on February 11, on the 6th day of the ascent, the team left the entire bivouac at the "Cross" level, took 3 ropes, and started moving to the summit in "Non-stop" mode. At 13:00, having passed 7 ropes above the 4 fixed from the platform, we reached the Ak-su ridge. The ridge is about 10–12 ropes of 4–5 category climbing, with traverses and rappels, which, combined with strong wind and an altitude over 5000 m, in winter conditions, is a problematic task. We needed 8.5 hours of continuous work to pass it. It should be noted that the Ak-su ridge was passed for the first time in winter. At 21:30 on February 11, 2013, the team reached the summit! We did not find a note on the summit, and we were unable to write one due to very strong winds; as proof of our presence on the summit, we left a rock hook in the cairn.
The descent on ready-made stations took the whole night, and by 11:00 on February 12, 2013, we descended to the platform at the "Cross" level. It took about 30 hours of continuous work to reach the summit and descend!
On February 13, 2013, having descended 20 ropes, the team returned to the base camp. There were no injuries, frostbite, or serious emergencies during the ascent.
