KATMANDU, Nepal (AP) — The rescuers moved quickly, minutes after the first block of ice tore loose from Mount Everest and started an avalanche that roared down the mountain, ripping through teams of guides hauling gear.

But they couldn’t get there quickly enough. No one can move that fast. Not even the people who have spent their lives in Everest’s shadow, and who have spent years working on the world’s highest peak.
