A massive ice block above Everest Base Camp has shut down the 2026 climbing season, holding up hundreds of climbers and Sherpa guides during the critical spring window. The Khumbu Icefall's shifting seracs and accelerating melt from global warming make this blockage a sign of worsening conditions, not a routine hazard. Alternative routes exist — the Sundari Route discovered in 2021 bypasses the Icefall entirely and deserves serious adoption.
