A massive, unstable ice block stalls Everest climbers at base camp
Hundreds of climbers and guides are waiting at Mount Everest's base camp after officials identified a massive, unstable ice block on the route to the first camp

A massive ice block on the primary route just above the Mount Everest base camp has forced hundreds of climbers and their local guides to delay their attempt to scale the world's highest peak. Officials reported the situation on Friday, noting that the obstruction has halted progress for numerous expeditions currently stationed at the mountain's base.[1][2]
The hazard is a serac, or a large block of glacial ice, located on the section of the climb between the base camp and camp one. Himal Gautam of Nepal’s department of mountaineering confirmed that the formation is considered unstable and presents a high level of risk for climbers. Experts are currently assessing the route to determine the best course of action for the hundreds of people waiting to proceed.[1]
This delay comes at a critical time for climbers who typically wait for specific weather windows to make their summit bids. The presence of such a large and unstable obstacle in a high-traffic area of the mountain creates a significant bottleneck, as safety remains the primary concern for the department of mountaineering and the local guides responsible for fixing the route.[1][2]
