During our expedition of 2021, there were no deaths but there were a few helicopter evacuations due to snow-blindness or altitude sickness/edema. Due to being on fixed lines for almost the entire climb, I would classify the actual route as relatively safe compared to mountains with greater exposure when not fixed with ropes. The main cause for concern on Ama Dablam is the hanging serac above Camp Three. Climbers generally avoid climbing and camping below this serac although we camped there before our summit push. In 2006, a piece of serac fell and killed six of the climbers in Camp Three. Three more climbers were also killed below the serac in 2014. Nepali climber Thundu Sherpa was killed when an earthquake in 2016 triggered an avalanche on the face.
