New Insights into Castle Peak Avalanche Incident

A recent report has provided new insights into the Castle Peak avalanche that occurred on February 17, 2026, northeast of Donner Summit in the northern Sierra Nevada, resulting in the deaths of six skiers and three guides.

The preliminary findings, released by Blackbird Mountain Guides, were compiled by avalanche expert Don Sharaf. The report analyzed weather data, guide records, GPS tracks, and interviews to understand the decision-making process of the guides and the group's route. It noted that the group attempted to reach safer terrain but was hindered by an uncrossable creek, while an alternate route was avoided due to concerns about trespassing on private property.

The report also examined the spacing of the victims, suggesting that the guides may not have recognized they were in an avalanche path due to the terrain's characteristics. However, it did not determine the cause of the avalanche, stating that it remains unclear whether it was triggered naturally or by the group's weight. Blackbird Mountain Guides expressed their sorrow over the incident, emphasizing the ongoing need for understanding and healing within the community.
