Three members of a Latvian climbing expedition have died in an accident high on Mount McKinley in Alaska’s Denali National Park, according the Latvian Mountaineering Association. A fourth climber was rescued and is in critical condition, the organization said.
Mount McKinley, with a summit of 20,310 feet above sea level, is the highest peak in North America. The accident occurred on Wednesday at about 18,000 feet, according to the U.S. National Park Service. That led to a rescue attempt on Thursday amid unsettled but improving weather conditions.
On Friday morning, the Latvian Mountaineering Association said that Inese Pučeka, Vija Olte and Renārs Kunigs-Salaks were killed in the accident. Mārtiņš Bilzēns was in critical condition and transported to a hospital, the organization said.
The Park Service did not immediately confirm the deaths or the identities.
The mountain is well known as Denali, its Alaska Native name. Last year, the Trump administration reinstated the name that honored the former U.S. president William McKinley, who never visited the mountain and was assassinated in 1901.
The main climbing season for Mount McKinley typically runs from late April through mid-July. Most climbers are part of small, guided expeditions, and about 90 percent of them try to complete the West Buttress route. The Park Service said that there were more than 500 climbers on the mountain.
News of the accident broke on Thursday. The Park Service reported that four members of a seven-person expedition had fallen in the area of Denali Pass. Three of the expedition’s seven members returned to high camp on Wednesday night after trying to rescue the other four.
Denali Pass, at 18,200 feet, is between the last high camp, at 17,200 feet, and the summit. It is a steep and icy section of the climb where teams usually rope themselves to fixed “pickets” placed every 90 feet or so. It is considered one of the most dangerous parts of the climb.
