Purnima Shrestha warned the spring climbing season on Mount Everest could shrink after a large chunk of glacier fell onto the mountain’s standard Nepal-side ascent route. Shrestha, a Nepali mountaineer who reached Everest’s summit three times in 2024 and began her first push on 11 May, said that even if teams cut a corridor quickly, the window for safe summit attempts could be reduced — hitting climbers, guides and the local economy that depends on spring expeditions.

What happened on the mountain

A substantial mass of ice has come down onto the standard ascent route on Mount Everest at the height of the spring climbing season. The blockage sits on the path used by most commercial expeditions attempting the summit from the Nepal side.

Teams now face a race: either open a safe passage through or around the obstruction, or accept a reduced number of summit attempts this year. The main season already offers a narrow window of favourable weather, and when the route itself is compromised, carefully timed rotations, acclimatisation schedules and summit pushes become harder to manage.

Voices from the climbing community

Mountaineer Purnima Shrestha flagged the risk to the season, saying that even if teams can cut a corridor through the ice, the overall climbing window could be reduced. Shrestha, who summitted Everest three times during the 2024 season and began her first push on 11 May 2024, underlines how quickly plans can change on the mountain.

Expedition operators typically rely on predictable access through heavily crevassed sections such as the Khumbu Icefall. When a major block of glacier shifts, established lines can be rendered unsafe until rope-fixing teams assess and re-establish routes — a painstaking process that depends on experienced high-altitude workers.

Economic and local impacts

The spring Everest season is a major source of income for mountain communities. When the route is blocked, expeditions can be delayed, shortened or cancelled, cutting revenue for local workers and businesses.

  • Direct impacts: fewer expedition fees, reduced guide and porter wages, lost contracts for local suppliers.
  • Supply-chain effects: lower demand for oxygen, ropes and equipment; cancelled or changed hotel bookings in Kathmandu; disrupted flights into the Solukhumbu region.
  • Community consequences: many Sherpas and high-altitude guides rely on spring climbs for annual earnings, so a compressed season can mean lost income for households and small firms in Lukla and Namche Bazaar.

Political and regulatory angle

Nepalese authorities oversee permit issuance and safety regulations for Everest climbs. A major route obstruction can prompt calls for rapid safety assessments and renewed debate in Kathmandu about how to balance access with oversight, because mountaineering income supports local government coffers and regional development projects.
