Climbers have left Camp 3 for their summit bid, half have already turned back due to the cold and fear of frostbite. The weather window has narrowed, now higher winds moving to K2 early Saturday morning, around dawn, basically 30 hours from the time of this post. They need to get up and down now, or turn back. The wind chill near the summit is -70F/-57C. There are 10 or less still pushing for the summit.
The few climbers who have made it high on K2 have started their summit push, late Thursday night K2 time. Another medical evacuation from K2 Base Camp, this makes three this season. Climbers are nearing the summit as the winds return on Saturday. 20+ people still on the summit push, more than a usual summer season – the power of commercialization.
