Accident and Rescue Summary
Leading Up to the Accident

We will never know exactly what Michael’s thought process was on the day of the accident, but what we do know is, Michael was very familiar with the terrain and the route he traveled. He left his house in Marion, Utah, at the base of Hoyt Peak at approximately 8:30 AM and told his wife he’d be back around 3:00 PM. He rode his snow bike, following a summer road to the base of a broad, open, low angle south-facing slope below Hoyt Peak. Michael placed his up track in a safe location and skied two laps on the sunny slope. At 12:10 PM he checked in with his wife via text, indicating all was ok.
We can only speculate the series of events that occurred after the second run, but we retraced Michael’s third track, which suggests he descended the low-angle, east-facing ramp with the intent of skiing a north-facing run a couple hundred feet from the peak. Investigating the crown and discovering Michael's last turns lead us to believe he entered the slope heading east, intending to ski a much more committing and complex north-facing slope. We saw a very distinct set of ski tracks entering the slope. Given the structure of the snowpack and the characteristics of the avalanche, we speculate Michael had completed several turns on the slope before triggering the avalanche that ultimately caught, carried, buried, and killed him.

Rescue Summary
At 5:00 PM Friday, March 7th, the Summit County Sheriff's Office (SCSO) received a report of an adult male skier who had not returned home as expected.The individual was believed to have been skiing alone in a backcountry area near Hoyt Peak, located northeast of Kamas City.
Search and Rescue (SAR) resources were immediately deployed, and a coordinated search was initiated. During the initial search, SAR teams identified an area with relatively fresh avalanche debris and performed a transceiver search, but no signal was detected. At that time, it was unclear whether the overdue skier had been involved in the avalanche. Due to extremely hazardous conditions, SAR commanders decided to temporarily suspend the search late on March 7, with plans to resume operations at first light on March 8.
A debrief with personnel and Incident Site Commander late Friday evening concluded additional resources were needed to assist with avalanche mitigation, allowing searchers to operate safely and effectively.

0700 Teams assembled at Summit County SAR HQ to formulate plans
0740 UAC Forecasters picked up from IC and surveyed the scene by air to provide Canyons Snow Safety team imagery for avalanche mitigation surrounding the accident scene.
0755 UAC Forecasters dropped back at IC
0800 DPS helicopter headed for fuel and to Canyons Village to pick up a mitigation team.
0905 Canyons Snow Safety lands at IC and preps for control work to the accident scene.
0935 Summit County Search and Rescue, Wasatch Backcountry Rescue. Canyons Snow Safety, and UAC Forecasters arrive at the accident scene at Hoyt Peak.
1005 Crews begin rescue and recovery efforts at the accident scene and work the debris with two dog teams.
1045 Dog 1 signals on the avalanche debris, a probe strike reveals a ski.
1047 Dog 1 signals again 10’ up slope on the debris, blood is noted on the snow.
1049 Positive probe strike reveals burial at 50-80cm.

Tragically, the overdue skier was found deceased. It was determined that the individual, 51 year old Michael Janulaitis from Marion, Utah had been caught in the avalanche. Michael was not wearing an avalanche transceiver.Huge thanks to Summit County Sheriff and SAR teams in coordination with the Department of Public Safety, Park City Mountain Resort and Canyons Village Snow Safety and Ski Patrol teams, along with Wasatch Backcountry Rescue for the hard work recovering Micheal and returning him to his family.
Terrain Summary

Measuring 43 degrees in slope steepness, this is unforgiving, complicated, treed terrain with several mid-slope breakovers adding to the complexity.

Powder blasted trees indicate the velocity and severity of the slide.

Weather Conditions and History
Late October and early November storms delivered shallow coats of early winter snow to the western Uintas. A substantial shot of Thanksgiving moisture provided some substance and created enough base to kick off the winter season. However, the moisture tap dried out as the jet stream shifted far to the north of the Uinta region. This set the stage for a weak snowpack and basal faceting, along with a few early season avalanches. However, the blueprint for a structurally challenged snowpack was written. A powerful holiday storm stacked up a couple of feet of dense, heavy snow, producing a widespread avalanche cycle as winter returned from its hiatus during the Christmas and New Year’s holidays.
Storm systems lined up on the West Coast and looked promising going into the New Year. However, those hopes faded as most of the energy evaporated once they came onshore. Dribs and drabs of moisture would offer the remnants of once robust storm systems, but they lacked substantial snow water equivalent (SWE), which would help the snowpack gain strength. Unusually cold mid-January temperatures combined with a two-week dry spell, set the stage for another round of faceting.

Skier triggered avalanches on February 8th near Hoyt Peak, breaking to weak January snow.
Early February was marked with a warm, wet, and very windy storm, but little snow accumulated near Hoyt Peak until February 7th when the Redden Mine SNOTEL recorded 4” of snow and .60 SWE. Near Hoyt Peak, storm totals are slightly more… 6” snow with .80” SWE. During the height of the storm, south and southwest winds crank in the 40’s (mph) and blast into the 70’s near the high ridges. Post-frontal cold air delivers 4” of low-density snow to wrap up the storm on the 8th.
Clear, cold weather settles in from the 8th through the 13th, though a multi-day storm was on the horizon, slated to settle into the region beginning mid-month.An Avalanche Warning is issued on the 14th, and the Valentine’s storm cycle churneds away for 48 hours, stacking up 15” of snow and 1.7” H2O at Redden. Higher in the drainage and closer to Hoyt Peak, 20” of snow with 2.2” SWE piles up. Nearby ridgelines experience steady west and southwest winds blowing 30-50 mph throughout the storm.
Four inches of low-density snow falls on the 20th, but the storm track shifts north once again, and February wraps up with high pressure and warming temperatures.

February started off slow, with two small storms delivering barely an inch of SWE. However, the mid month Valentine's storm got things rolling with strong winds and two distinct impulses totaling 4.1" of SWE and nearly 36" of dense heavy snow. Above is a data run from nearby Redden Mine (8,540') sno-tel site.

Snow Profile Comments
The Western Uinta’s are known for their shallow, weak and continental-esque snowpack, the 2024-2025 season is no different. At the time of the accident, the upper snowpack consists of 1’ of storm snow resting on a dense, strong slab on top of a crust with a thin layer of facets beneath it. The lower pack has weak snow from a dry period in January, with some lingering hard snow below, and the base of the snowpack consists of weak snow from the early season.

Forecaster Coments and Conclusions-
It was not unusual for Michael Janulaitis to snow-bike and ski solo. But like all lone mountaineers, this manner of travel left him vulnerable to the slightest gear malfunction, injury, or other mishap… let alone triggering a large avalanche with no one to assist in the rescue.
The route, the terrain, the local weather and snowpack complexities, and the mode of travel were all very familiar to Michael. However, it is probably this familiarity that led to a feeling of comfortability. Unfortunately, with no one to interview, there are lots of gaps and many unanswered questions. We can only speculate on Michael’s decision-making and objectives by retracing his tracks and offering our evidence.
We are deeply saddened by this tragedy. We thoroughly investigate avalanche accidents and share our findings to hopefully learn more about the contributory factors leading up to the incident. Our ultimate goal is to offer transparent findings, share those thoughts with our community, and help prevent another backcountry avalanche accident.
