The Incident
In February, a backcountry ski party of 15 left the Frog Lake Huts during a major snowstorm near Lake Tahoe. While traversing avalanche-exposed terrain near Castle Peak, a 400-foot-long slab avalanche struck, burying nine skiers between five and eight feet deep. All nine victims died of asphyxiation; three guides and six clients were among the dead. Five clients and one guide survived.
Background & Context
The group was led by Blackbird Mountain Guides, a Truckee-based guiding company. Avalanche danger at the time was rated “high” by the Sierra Avalanche Center, one level below “extreme.” Prior to the slide, two separate groups combined to return to the trailhead at Castle Peak Snowpark on Donner Summit, moving through terrain flagged as high-risk.
Data & Statistics
- Fatalities: nine (six clients, three guides)
- Survivors: six (five clients, one guide)
- Burial depth: reports indicate victims were buried 5–8 feet deep; autopsy narrowed this to 5–6 feet.
- Avalanche size: roughly 100 feet wide and 400 feet long.
- Danger rating: “high” (Sierra Avalanche Center).
- Survival odds: studies note burial deeper than two meters (?6.5 feet) yields about a 10 % chance of survival, while burial under half a meter (?1.5 feet) yields roughly an 80 % chance.
Official Statements & Responses
The Nevada County Sheriff’s Office, which operates the coroner service, said sections of the coroner’s reports were heavily redacted to protect families’ privacy. Sheriff’s Office spokeswoman Ashley Quadros explained the redactions were intended to safeguard against unwarranted public exploitation of graphic medical details.
District Attorney Jesse Wilson’s office continues to review the case, and the sheriff’s department indicated that a criminal-liability investigation remains open.
Cal/OSHA confirmed an ongoing investigation into possible workplace-safety violations involving the guiding company.
Criticism & Opposition
An April report by the U.S. Forest Service National Avalanche Center and the Colorado Avalanche Information Center concluded that basic safety practices were not fully observed. The report noted the party traveled together through avalanche terrain and entered the run-out zone, contrary to the accepted best practice of exposing only one person at a time.
Conflicting Reports & Gaps
The coroner’s findings confirm asphyxiation as the cause of death, but the reports do not clarify whether any victims sustained additional traumatic injuries before burial.
The reports are partially redacted, leaving unanswered questions about possible drug or alcohol presence, the condition of bodies prior to burial, and whether any avalanche-airbag backpacks deployed.
The precise trigger of the avalanche—natural versus human-induced—remains undetermined, with experts offering differing assessments.
What’s Next
The Nevada County District Attorney’s office will continue its review of potential criminal negligence.
Cal/OSHA’s investigation into workplace-safety compliance is ongoing.
Further details from the coroner’s office may be released as redactions are reconsidered, potentially shedding light on additional injuries or contributing factors.
