Aosta, November 27 - Searchers are continuing to look for three Italian climbers missing on the Dome des Ecrins in the French Alps since Monday. By Tuesday, more than one meter of snow had fallen in the area where the trio - including two doctors and an instructor - began climbing on Saturday. All three are experienced climbers but their itinerary has been classified as "very difficult". Contact was last made late Monday afternoon. Searchers hope the trio has found shelter from the snow and falling temperatures.
