Slab Avalanche Sweeps Mountaineering Group Into Lake, Killing Three at Ski Portillo, Chile
A large slab avalanche claimed three lives at Ski Portillo, Chile, on Saturday, October 17, 2026, according to a press release from the resort.
“The ski resort closed for the winter season on Sunday, October 11, and the area where the accident occurred is outside the designated ski area,” writes Ski Portillo. “Entering closed areas, or continuing an activity despite warnings, means exposing oneself to serious hazards that can endanger the lives of both those who enter and the teams who must come to their aid.”
Authorities say a group of mountaineers was participating in an unapproved expedition around Laguna del Inca, the famous lake in the center of Ski Portillo. The large avalanche swept multiple people into the lake, trapping them under avalanche debris and ice.
Multiple agencies were deployed for rescue operations, including volunteer firefighters, Carabineros police, an air police helicopter unit, medical teams, and SENAPRED regional personnel. Rescuers arrived on scene within 10 minutes and managed to rescue four people, according to SENAPRED.

Ski Portillo has recorded more than double its annual average snowfall, 1254 cm (493 inches), and the snowpack remains deep despite the resort being closed for the season. As spring temperatures rise, wet avalanches and dramatic snowmelt are expected.
Two of the victims have been identified as Chilean nationals, Magdalena Acuña Jiménez, 56, and Rodrigo Peña Troncoso, 36, according to The U.S. Sun.
The resort expressed its condolences, and offered a word of caution:
“We once again extend our condolences to the victims’ families and reaffirm our support for the work being carried out by the authorities.
Mountaineering activities must be undertaken responsibly and in compliance with all safety instructions and restrictions. Ski Portillo has clearly visible signage, both at the hotel and in various areas of the slopes, warning of the danger of death and prohibiting entry into restricted areas. These warnings are also posted on our website. Mountaineering and any activity in high-mountain environments requires preparation, constant assessment of conditions, and above all, personal responsibility and strict adherence to safety guidance. We would like to remind the public to be cautious when engaging in these activities and that no experience should ever take precedence over the protection of life.”
