Castor 4223m summit view

Looking back down the magnificent summit crest. Just beyond the trail ascending top part of SW flank route is in view - at the point of crossing the bergschrund, at start of the 'crux' of the route. In the near background the Weisshorn dominates left skyline and the summits of Tashhorn and Dom (to a lesser extent Alphubel) the right. In the far background are the summits of the Bernese Oberland. 11th September 2014.
