Large Ice Block Blocks Mount Everest Climbing Route, Delays Spring Season

Apr 24, 2026, 09:07

Introduction

A large block of ice, known as a serac, has blocked the main climbing route on Mount Everest near the Khumbu Icefall. This has caused a delay in the spring climbing season for hundreds of climbers who have permits.

Main Body

The ice block is about 30 meters high and is located about 600 meters below Camp 1 on the Nepalese side. It has stopped the team of specialist Sherpas, called ''icefall doctors'', from completing the annual route preparation. They usually fix ropes and ladders, but they have been unable to get past the serac for nearly two weeks. According to Himal Gautam, spokesperson for Nepal''s Department of Tourism, the serac is a natural feature that cannot be removed or changed. Authorities can only watch it and wait for it to melt or collapse. Dawa Jangbu Sherpa, an icefall doctor, stated that the team expects the serac to clear within a few days as its lower part weakens. Meanwhile, the Sagarmatha Pollution Control Committee, which manages the route-laying team, plans to do an aerial survey to check the serac''s stability. The risk of an avalanche remains high. In the meantime, the Department of Tourism is considering airlifting rope-fixing teams and equipment directly to Camp 2. This would allow them to open the upper part of the route while the lower part is still blocked. The delay has shortened the already limited climbing window, which usually ends by late May. Nepal has issued 410 permits for foreign climbers this spring, close to the record of 479 in 2023. A temporary camp of about 1,000 climbers and support staff has formed at base camp, waiting for the route to open. Some climbers have expressed concerns about the compressed schedule. Nepali mountaineer Purnima Shrestha warned that it could lead to overcrowding and traffic jams on the summit route. The Khumbu Icefall is one of the most dangerous parts of the climb. Historical events show the risks: in 2014, a serac collapse caused an avalanche that killed 16 Sherpa guides, one of the worst incidents on Everest. More recently, in 2023, three Nepali guides died after falling ice swept them into a crevasse. Despite higher permit fees—now $15,000 for foreign climbers—demand for Everest expeditions remains strong. Mountaineering is a major source of income for Nepal.

Conclusion

The spring climbing season on Mount Everest is delayed because of a large serac blocking the Khumbu Icefall route. Authorities are using two approaches: waiting for the ice to melt naturally and considering alternative ways to open the upper mountain. The shorter timeline raises the risk of more congestion, a common problem on the world''s highest peak.
