There has been difficult snow conditions which has prevented the K2 North Ridge Expedition from reaching camp 2. Instead they have bivouac most likely at the intermediate camp, though this is not certain right of now.
The progress has been slow and it has been snowing for all but 2 hours of their climb today.
Ralf Dujmovits decided to turn back to camp 1 at 5350m. The avalanche danger was too great.
