Today, LeDuc -- still eager to tick the last two summits off her list -- is on a two-year assignment in the West Bank for the Canadian International Development Agency. Kedroswki, whose blog became a way for people to follow the deadly 2012 Everest season, is writing a book about his experience.
He's also outlining potential policy that could regulate Everest like other peaks, including Mount Rainier and Mount McKinley in the United States, have in place.
Ben Yehuda hasn't let his damaged right hand hold him back. He's led an expedition in Georgia and solo climbed pyramids in Spain. Still with the army, he's working toward degrees in law and political science.
Large parts of the hand are still numb and he has to type school papers, but the threat of amputation has passed. Ice climbing can be painful, so he uses special equipment to support more body weight, relieving his hand of the burden.
Things will never be the same, but he's adapted. There's a joy in his voice, despite what transpired in 2012. He doesn't see his aborted attempt as a failure. After all, rescuing Irmak was a success.
The ghosts of Everest still haunt him, and the climbing notebook that accompanied him remains unopened, though he takes it everywhere. It contains his notes and poems from that journey, but it's missing the last three days.
"One day I will have the time and peace to open and read it," he said. "I don't know what's waiting for me in there. That's the scary part. But it's with me, all the time."
Ben Yehuda echoes the words of other climbers: Everest is a choice. You can stay at the base or you can climb, but the consequences of the latter become clearer the higher you go.
"The closer you get to the summit, you suffer more and more because you have that choice, and you hate the fact that you have that choice," he said.
His choice now? Returning to the Himalayas in September.
