For three days, Nepalese mountaineer Dawa Sherpa was trapped deep inside a crevasse on Everest, surviving on biscuits, chocolates and chunks of ice, while back home his family had already begun mourning his death.

Dawa himself had nearly given up hope of rescue, until an avalanche thundered into the 8-meter deep ice crack, filling it with snow and creating a route to freedom.

¡°I am very happy to be back, I thought I would die there,¡± Dawa, 57, said, giving his first full account of his dramatic escape as he recovers in an apartment in Kathmandu with his family.
