A glacier collapse on Langtang Lirung, a 23,734-foot peak near Nepal's border with Tibet, triggered a 60-mile flood of water, mud and debris on Wednesday. By Friday, Nepal's National Disaster Risk Reduction and Management Authority confirmed 579 deaths with many more missing. The disaster followed the July 30 avalanche on Broad Peak in Pakistan's Karakoram range that killed celebrated Nepali mountaineer Nirmal Purja and nine others. Mingma Gyalje Sherpa, founder of Imagine Nepal, led the body recovery expedition.

Scientists and climbers warn of accelerating ice loss across the Himalayas. Glaciologist Arbindra Khadka at Tribhuvan University in Kathmandu says Himalayan glaciers lose about a meter of ice annually. "The entire Himalayas are melting," he warns. Tourism represents 6.1% of Nepal's economy and supported 1.2 million jobs in 2023. Over 1.16 million international visitors arrived in 2025, with 165,056 trekking. This spring, 1,195 climbers obtained permits for 31 mountains, generating $9 million in royalties.

Tul Singh Gurung, president of Nepal National Mountain Guide Association, notes disappearing snow exposes rockfall hazards. "Every mountain has a rockfall problem," he said. American mountaineer Dave Watson, a seven-time Everest summiteer since 2004, confirms hazards exist in "lower volume" historically. The changing mountains threaten livelihoods where successful guides earn 10 times ordinary Nepali salaries.
