New exclusive footage obtained and verified by The New York Times gives the clearest view yet of the Aug. 26 Langtang Lirung collapse that triggered the catastrophic Nepal–Tibet floods. Hikers heard a huge crack before ice, rock and debris plunged into the valley, throwing up an enormous dust cloud. Another video captures debris racing downhill immediately after the collapse—the beginning of the disaster that would devastate communities downstream.
