A massive storm slab broke loose near Castle Peak, just outside Lake Tahoe. Fifteen skiers on a three-day backcountry tour with Blackbird Mountain Guides were heading back when the mountain gave way. Nine dead. The deadliest avalanche in America in more than forty years.
Here are the different takes:
1. Preventable (Public Critics)
The conditions said turn back. They didn't.
The rating was a 4 out of 5. The advisory language was unambiguous. Backcountry skier Kurt Gensheimer, who was at the site through Sunday but left before the storm: "absolutely a preventable tragedy." A Lake Tahoe local on TikTok: "These businesses have no business operating on days like today."
Professional guides exist to make the call. That's the job. Read conditions, protect clients. The conditions screamed no. The comments section is a wall of the same question: why were they out there?
2. It's Complicated (Guiding Community)
Nobody in the guiding community has defended Blackbird. But the private counterargument is forming.
Multi-day tours create their own logic. You're already out there. Weather changes faster than plans. Evacuation routes can become as dangerous as staying put. The calculus isn't as clean as "the forecast said don't go."
These aren't amateurs. Blackbird was ranked #1 by the American Institute for Avalanche Research and Education in both 2024 and 2025. No prior incidents. The day before the avalanche, they posted on Instagram documenting "atypical layering" and a "particularly weak layer." They were tracking conditions actively.
The silence matters. Blackbird hasn't explained why the tour continued. The Nevada County Sheriff's Office is investigating. Decisions made on a mountain in real time may look different from the inside.
3. Broken Frameworks (Risk Researchers)
There's a third position neither camp is engaging with: the frameworks we rely on don't work the same way anymore.
The global pattern says something. The same week, the Western Alps had roughly 75 avalanche deaths this season, with at least 25 in France alone, above the ten-year average. More people are skiing off-piste than ever. Better gear makes people feel safer, which sometimes makes them less careful.
Climate is changing the snowpack. The weak layer beneath the Castle Peak slab formed during a dry spell. But the speed and intensity of the storm that loaded on top of it was unusual. Avalanche decision-making is probabilistic, not binary. That spectrum collapses when historical behavior stops being predictive.
Where This Lands
Public critics say it was reckless. Guides will say the ground truth was more complex. Climate researchers worry both camps are missing the structural problem.
