The Trê-la-Tête rockfall onto the Glacier de la Lex Blanche, Mont Blanc Massif, Italy, in September 2008
In September 2008, a large rockfall (50,000 m3) detached from 3470 m a.s.l. on the east-facing spur of Aiguille de Tré-la-Tête, in the upper part of the Val Veny (Valley of Aosta). It travelled for > 1 km onto the steep Petit Mont Blanc Glacier, the main tributary of the Lex Blanche Glacier. It i...
