What happened

The episode as NWS SLC wrote it up.

Following a strong mid-month winter storm which produced substantial mountain snow accumulations, many avalanches were reported across Utah's mountains due to snowpack conditions.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Salt Lake City, UT wrote its last area forecast discussion before the first event at Feb 21, 3:29 AM MST, 6 hours 46 minutes earlier. Its key messages:

  • High pressure will bring dry and increasingly mild conditions for the weekend and into early next week.
  • There is a high (90%) chance of valley rain and mountain snow next Tuesday/Wednesday.

.KEY MESSAGES...

- High pressure will bring dry and increasingly mild conditions
  for the weekend and into early next week.

- There is a high (90%) chance of valley rain and mountain snow
  next Tuesday/Wednesday.

&&

.DISCUSSION...Dry and stable conditions have settled into the area
as high pressure builds across the Great Basin. There are some
areas of dense fog across Cache Valley and Uinta County, Wyoming
given the snowpack. This fog will burn off by mid morning.
Otherwise, conditions are very cold across the entire region, but
the warming trend will begin today as heights build and
temperatures warm aloft.

Temperatures will gradually warm through early next week with high
temperatures running about 10F warmer than normal for most
locations. Conditions will remain dry and stable through early
next week before valley rain and mountain snow return for the
northern half of the CWA Tuesday and Wednesday of next week.

A deep elongated trough with a 150 kt jet will become established
between Hawaii and the west coast. This will pull moisture into
the western CONUS in the form of an atmospheric river by early
next week. Cold air will be lacking with this system as zonal flow
will remain in place. Snow levels will be between 7000 to 8000
feet. All ensemble members are now on board with bringing
accumulating precipitation to the northern half of the CWA with
only ~17% of members bringing precipitation to the southern half
as well. This moisture will get cut off by a ridge building across
the west coast by Thursday and Friday leading to more dry and
stable conditions with warmer than normal temperatures.

&&

.AVIATION...KSLC... VFR conditions will prevail through the TAF
period. Winds will remain southerly though the period, with a 30%
chance of winds temporarily shifting to northwesterly during the 23-
02Z timeframe.

.REST OF UTAH AND SOUTHWEST WYOMING...Patchy dense fog resulting in
LIFR to VLIFR conditions will continue around KLGU through 16Z
before conditions improve. There is a 30% chance for LIFR or lower
conditions in dense fog around KHCR through 16Z as well. Otherwise
VFR conditions with light diurnally driven winds can be expected
across the area through the TAF period.

Two skiers left the Butler Fork trailhead in Big Cottonwood Canyon Saturday morning 2/21 with the plan to do a run known as The Triangle. This is in Butler Basin, a Big Cottonwood Canyon drainage east of Gobblers Knob. The skiers ascended a steep north-facing slope next to the desired run, when near the top an avalanche broke. Both skiers were caught and carried around 100 feet down the slope, becoming fully buried at the bottom. Other groups of skiers in the basin witnessed the avalanche occur, and notified 911, Alta Central, and began rescue efforts. Around 10 minutes after the avalanche, one of the bystanders made their way to the debris, conducted a beacon search, and eventually found a splitboard binding still attached. Additional bystanders arrived and helped uncover the first victim, cleared their airway, allowing them to breathe and gain consciousness. The victim had suffered a leg injury, but was moved to a safer location. Around this time others began transceiver searching for the other victim, eventually exposing the boot. The skier was buried around 150 cm and face down. The second victim was unburied and CPR efforts were initiated. An EMT was longlined to assist the first victim who had regained consciousness, and the second victim was airlifted from the scene but later succumbed to their injuries.

A group of seven snowbikers met in Big Cottonwood Canyon and the Guardsmans Pass trailhead with the intention to ride in the area during the afternoon. Most of the group had extensive backcountry, including formal avalanche training, and members of the group were equipped with transceiver (though no transceiver check was performed), probe, shovel, and avalanche airbag. While they were aware of the conditions, including considerable avalanche danger rating (per Utah Avalanche Center), they set out planning to stick to low-angle slopes in Caribou Basin which they knew well. While riding, they observed numerous avalanches, and noted the loose underlying snow characteristics when getting one member unstuck from deep snow. After taking a break, the group decided to do one more session around the basin before returning to the trailhead. The group set out and subsequently regrouped, but noticed one member was missing. They backtracked and found a spot where a fresh avalanche had overrun an area which they had ridden. The members called 911 and began a transceiver search, but could not find a signal given the large debris pile. Eventually after several minutes, one member spotted the missing member's snowbike. The group began spot probing, but were unsuccessful. Wasatch Search and Rescue and AirMed responded to the site, but due to conditions getting dark and the likelihood further avalanche mitigation would be required for rescuer safety, rescue efforts were halted for the night. Multiple agencies resumed rescue efforts, and avalanche mitigation was performed. In time an avalanche dog located the missing member, and the victim was found deceased beneath roughly 2 feet of snow. The victim was wearing an avalanche transceiver, but it was not turned on. Additionally, the avalanche airbag the victim had been wearing had not been deployed.

The people who died

As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
