DENALI NATIONAL PARK, ALASKA — A 41-year-old climber has died after falling nearly 3,000 feet while attempting to summit Mount McKinley, also known as Denali — the highest peak in North America — according to a statement from the National Park Service (NPS).
Alex Chiu, who was climbing with two companions on the West Buttress route, reportedly fell Monday at a notoriously dangerous location called Squirrel Point, a steep section along the popular ascent path. The incident occurred at approximately 16,000 feet elevation.
After witnessing the fall, Chiu’s climbing partners attempted to descend toward the drop point but were unable to see or hear him, according to the NPS. With conditions worsening and no sign of Chiu, they were forced to retreat down the mountain to seek help.
Rescue Hindered by Harsh Conditions
Harsh weather conditions, including high winds and heavy snow, delayed rescue efforts. Teams were unable to reach the area until Wednesday morning, two days after the fall. Chiu’s body was located shortly after.
The National Park Service confirmed the death in an official news release and offered condolences to Chiu’s family and fellow climbers.
“Our hearts go out to the loved ones of the climber who lost his life in the unforgiving terrain of Denali,” said one NPS spokesperson. “Mountaineering in Alaska presents extreme challenges, and every year we are reminded of the risks.”
A Deadly Pattern on Denali
The fall occurred along the West Buttress route, Denali’s most frequently used path, known for its accessibility relative to other ascent lines — but still extremely dangerous. Since 1980, numerous climbers have died in falls along this section of the mountain, the NPS noted.
Denali rises to over 20,000 feet and is a popular destination for experienced mountaineers worldwide. The current climbing season runs from early May through early July, with approximately 500 climbers currently on the mountain, according to park officials.
Chiu’s death is the latest in a long line of fatal incidents on the mountain, prompting continued calls for rigorous preparation and situational awareness during expeditions.
A Reminder of the Risks
Mountaineering experts emphasize that even well-prepared climbers face serious dangers on Denali, including sudden weather shifts, avalanche risk, and steep, icy terrain.
“No matter how skilled you are, Denali demands absolute respect,” said one Alaskan climbing guide. “The mountain doesn’t forgive mistakes — especially in sections like Squirrel Point.”
The National Park Service advises all climbers to undergo proper acclimatization, carry emergency communication devices, and review weather forecasts constantly when ascending Denali.
Ongoing Monitoring of Climbing Season
The NPS continues to monitor activity on the mountain closely during the 2025 climbing season, offering logistical support, safety briefings, and emergency rescue services. No further accidents have been reported this week.
