The pictures from/of helicopters are great.
However, the two pictures "looking from Everest Camp 2" with the red circles identifying climbers (posts 512, 513), the following one of the avalanche (post 514), and the picture of the Crosshair Couloir (post 516), are of Annapurna, taken by Tunc Findik. See a stunning report of the circumstances at
The Day the Mountain Fell….Part 1 | Don Bowie.
Why do you claim "3 still lost"? From the above website, "You may not believe this, not only did all the climbers survive this avalanche, but not one was hurt. Not even a little."
