Aiguilles du Diable — L'Isolée

The 'isolated one' — the most slender and southernmost of the five Aiguilles du Diable, the granite needles arrayed on the south ridge of Mont Blanc du Tacul. L'Isolée was the last of the five to be climbed: on 4 August 1925 by the great Chamonix guide Armand Charlet with Jules and Henri Simond, completing the set after a long campaign of attempts. Charlet would go on to make the first integral traverse of all five needles in 1928 with Camille Devouassoux and the American Bradford Washburn — a route now regarded as one of the supreme classic granite traverses of the range.
