According to Fredrik Ericsson no one has yet to reach the base camp of K2. There is a Swiss group that has persevered through deep snow and reached Broad peak, not far away.
As for Fredrik Ericsson and his climbing partner Trey Cook they have been climbing a peak called Laila. This is a beautiful mountain that caught their eye on their way to K2.
They had planned to climb the mountain and ski down it. However, on the way up they found that the snow was getting very deep. They paused and realized that there could be avalanches if they continued, so they turned back.
They have now left Laila Peak and are on their way again to K2.
