A tragic accident on Mount Makalu has claimed the life of American mountaineer Shelley Johannesen. According to reports from SnowBrains, the 59-year-old climber was caught in a major avalanche at approximately 7,000 meters while descending from the summit of the world's fifth-highest peak.
Johannesen, a co-founder of the U.S.-based outfitter Dash Adventures, had successfully summited the 8,485-meter mountain on May 9 alongside her climbing partner, David Ashley, and two mountain guides, Tawa Sherpa and Phurba Sonam Sherpa. The accident occurred on Sunday morning, May 10, as the team navigated a section of the route fixed with ropes just below Camp 3.
Rescue Efforts and Incident Details
The avalanche prompted an immediate response from climbers stationed at Camp 2. While rescuers were able to locate and extract Phurba Sonam Sherpa from the debris, Johannesen could not be saved. David Ashley and Tawa Sherpa survived the incident but sustained injuries; both were subsequently evacuated by helicopter to a hospital in Kathmandu for urgent medical care.
The incident has been documented by outlets including Explorer’s Web and the Tourism Times. The tragedy underscores the volatile nature of the Himalayan environment, even for experienced expeditions.




Context of Himalayan Mountaineering
This fatality is the second to occur on Makalu this spring. Earlier in the season, 38-year-old Czech climber David Roubinek lost his life to altitude sickness while attempting to climb Makalu II. As the season progresses, many teams are currently evaluating their next steps, with some shifting their focus toward Everest and Lhotse to take advantage of their existing acclimatization.
The loss of Johannesen serves as a somber reminder of the inherent dangers associated with high-altitude mountaineering, where changing conditions can turn a successful summit attempt into a life-threatening scenario in an instant.
