Nepal's female climbers blaze trails for their gender

When a deadly avalanche hit Mount Everest a year ago, Pasang Lhamu Sherpa Akita, one of the few Nepali women with expertise in climbing the world's highest peaks, headed straight there to help.

A gifted mountaineer who had summited Everest by the age of 22, she is part of a new generation of Sherpa women who are climbing peaks that have traditionally only been scaled by their men.
