“A powerful winter storm moved by means of the realm from February 15 by means of February 19,” the report states.

On the exact hour the avalanche ran, situations had been at their most excessive and importantly it was accompanied by very robust winds that loaded some slopes.

 “The avalanche occurred on a slope the place the wind had redistributed the snowfall, piling it into drifts far deeper than the quantity measured at close by climate stations.”

We reported on the incident on the time on PlanetSKI:

It’s the worst avalanche incident within the US since 1982 when seven folks died within the Alpine Meadows Ski Resort close to Lake Tahoe, in California.

The deadliest avalanche recorded within the US was in 1910 in Wellington, Washington, the place 96 folks had been killed after a big avalanche swept two Nice Northern passenger trains right into a gorge.

On the morning of February 17, the members of those two guided teams from the identical information service had been mixed right into a single group with 4 guides for the return to the trailhead.

Sooner or later earlier than the avalanche launched, two members of the group fell behind.

Information #4 within the again was aiding Shopper #11 with a ski binding toepiece subject.

That tools failure, the report would later notice, possible saved their lives.

The report attracts on survivor testimony printed by the New York Occasions on February 28, 2026, to reconstruct the moments of the avalanche itself.

The report was unable to find the reason for the avalanche,

“A ski information within the group yelled ‘Avalanche’ and Shopper #10 regarded as much as see a wall of white with unusual blurs of colours,” the report states, quoting the account within the New York Occasions.

“He realized that the colours had been the tumbling skis and clothes of the opposite skiers. He dove behind a useless tree and was rapidly buried by the avalanche particles.”

Shopper #11 and Information #4, nonetheless behind with the binding restore, reached the remainder of the group moments later and located a particles discipline.

They’d not seen the avalanche happen.

The report additionally confirms for the primary time that a number of members of the group had been outfitted with avalanche airbag backpacks.

None was deployed on this accident.

The crown was by no means seen as new snow was filling it in even because the slide ran.

“The avalanche is believed to have been a tender slab of dimension D2 to D2.5 with the precise weak layer and mattress floor unknown.”

It ran roughly 400 vertical toes, by means of bushes at mid-path and beneath.

SAR responders estimated the particles discipline at 100 toes broad.

Probably the most hanging new materials within the report is the step-by-step account of the companion rescue.

An account of how two folks, one a information and one a shopper, labored by means of a particles discipline in a blizzard with 125 mph wind gusts on the ridge above them.

Shopper #10 pressured himself out from beneath the particles and shouted that individuals had been buried, pointing to the final location he had seen his companions.

Information #4 started a transceiver search.

Shopper #11 noticed a ski pole protruding from the particles floor, and it was shifting.

He dug to search out Shopper #9, who “had an airway alongside his arm and pole as much as the snow floor and indicated he was not critically damage.

Information #4 situated Purchasers #8 and #7 through transceiver search and probe.

Each had been initially excavated solely sufficient to reveal their faces.

“Whereas digging for Shopper #7 they encountered the leg of one other group member and the backpack of yet one more group member.”

Persevering with to dig, the group uncovered Information #3 and Shopper #6.

Each had been assessed as exhibiting no indicators of life.

The report notes that the group then redirected to totally excavate Purchasers #7 and #8, each assessed as injured.

A choice was made to maneuver the six survivors downslope to a place away from the avalanche path.

“An emergency shelter was constructed by Information #4, and care was given to Purchasers #7 and #8.”

Shopper #10 had positioned a 911 name round 11:30 a.m., when the search started.

SAR groups had been dispatched, together with ski groups from the Citadel Peak trailhead, and snowcat groups heading towards the Frog Lake Huts through the Tahoe Donner Cross Nation Heart.

Tahoe Nordic Search and Rescue reached the accident web site at roughly 5:30 p.m.

By that time, roughly two toes of recent snow had settled over the particles discipline.

SAR responders might solely find the sides and toe of the particles by the depth their boots penetrated the snowpack: on the particles, they may stand and stroll.

Off the sting of it, they sank previous the waist.

TNSAR members discovered the eight remaining buried victims that night.

The report states they had been “all buried 3 to eight toes deep inside a 20′ x 20′ space.”

The binding failure which delayed Information #4 and Shopper #11 could have been the rationale each survived, and that their subsequent companion rescue instantly saved lives: “2 of the 4 buried survivors required companion rescue to excavate the snow that coated their airways. The speedy location and excavation of those two people was lifesaving.”This group traveled beneath avalanche terrain and thru the runout zone of an avalanche path throughout a interval when a pure or human triggered avalanche was prone to very possible.The accepted greatest observe of “exposing just one individual at a time to avalanche terrain” was not adopted.Group dimension mattered: “This group consisted of 15 folks. Evaluation of previous avalanche accidents has indicated that bigger group sizes (4 or extra folks) have greater probabilities of being caught in avalanches,” citing peer-reviewed analysis printed in Wilderness & Environmental Medication in 2016.
