Dark clouds gathering

... as we walked down the Ochsental Glacier, descending from Piz Buin. The saddle ahead of us is the Egghornlücke. We don't have to go over there, we're making a slow turn to the right before getting there. The peak in the center, to the right of the saddle, is the Silvrettahorn (3244m). We'll be up there tomorrow. 23 July 2013.
