From Madison Mountaineering:
During the last few days the weather and route conditions have deteriorated significantly on K2, causing many avalanches and also rock fall. The climate here has warmed up dramatically, and as a result snow slides down to the glacial ice have peeled off K2 and the surrounding peaks, in once case the snow avalanches buried another team’s advanced base camp, fortunately no one was there at the time. The weather forecast has much snow ahead as well as continued warm temperatures, so without any indication that conditions may improve we are abandoning our climb of K2. Yesterday, one member of our Sherpa team was injured by a falling rock, we flew him by helicopter this morning to Skardu where he is being attended to. We will close up our base camp over the next few days and then plan to head out, there is still a chance we will make a Broad Peak attempt, weather and route conditions permitting. We look forward to coming back for K2 next year!
