An avalanche on Machapuchare or Fishtail Peak in the Annapurna Himalaya, Nepal. It was caused by a massive block of glacial ice detaching from the summit cliffs of this 6993 metre tall peak on 29th December 2012. Such ice avalanches are more common in Spring and summer, as in winter, the ice is normally frozen and more stable. The avalanche descended around 3.6 kilometres, and covered trekkers on the valley path below in a dusting of snow.
