Glacier Blockage Delays Climbing Season on Mount Everest

Thu Apr 23 2026 21:10:24 GMT+0000 (Coordinated Universal Time)

A significant glacier blockage has emerged just as the peak climbing season commences on Mount Everest, leaving climbers and guides in a challenging situation as they await a potential melt.

A large, unstable chunk of glacier is obstructing the route to Mount Everest from Base Camp, creating delays in the climbing season. Known as a serac, the glacier stands 100 feet tall just below Camp 1, forcing climbers to wait for conditions to improve. The 'icefall doctors' responsible for preparing the route are currently unable to bypass the blockage, which raises concerns about potential traffic jams for climbers later in the season. Authorities are exploring options such as airlifting teams to expedite preparations.

A huge, unstable chunk of glacier is blocking the route up Mount Everest from Base Camp in Nepal just as peak climbing season gets under way in the Himalayas.

Icefall doctors – who fix ropes and ladders on the lower part of the route up the world's highest peak - can find no way around the 100-foot-high (30m) block of ice just under Camp 1.

They say the only option is to wait for the ice block, called a serac, to melt – which they hope will happen within days.

The delay means preparations are weeks behind schedule for the spring season when weather for Everest ascents is usually best, and fears are growing that climbers will be queuing to reach the summit again this year.

Purnima Shrestha, a prominent climber and photographer from Nepal, is currently acclimating to summit Everest for the sixth time.

We usually climb between Camp I, Camp 2 and Camp 3 back and forth during this acclimating process. Delays in the opening of the route have added concerns of possible 'traffic jams' to the peak this year, she told the BBC from Base Camp.

The icefall doctors work for the Sagarmatha Pollution Control Committee (SPCC), responsible for securing ropes as far as Camp 2 on Everest, which stands 8,848.86m (29,031 feet) above sea level. They reached Base Camp three weeks ago and would normally have fixed the route as far as Camp 3 by this time in April but are still blocked by the frozen chunk below Camp 1.

We haven't found artificial ways to melt it so far, so we don't have any options other than to wait for it melting and crumbling itself, SPCC base camp coordinator Tshering Tenzing Sherpa told the BBC.

Nepal's Department of Tourism is exploring different options, including airlifting teams to Camp 2, to expedite the route's opening. We will wait for the ice to melt at the place where there is an obstruction and work there when everything is safe, the department's director general stated.

Despite challenges posed by the situation, climbers remain hopeful that they will be able to devise plans to navigate the obstacles and successfully summit this season.
