Inbounds Avalanche at Silver Mountain Raises Questions After Fatal 2020 Slide

Michael FultonMichael Fulton

TL;DR

Two skiers were caught in an inbounds avalanche on a double black diamond run at Silver Mountain Resort in Idaho, despite patrol conducting avalanche mitigation earlier that day. Both escaped without serious injury, but the incident raises questions about a resort that permanently closed terrain following a fatal 2020 slide.

Two skiers caught in inbounds avalanche at Idaho resort despite morning control work

Two skiers were swept up in an inbounds avalanche at Silver Mountain Resort in Idaho on Friday afternoon, escaping without serious injuries in what marks the second significant slide at the resort in five years. The incident occurred around 4:30pm on Moonshine, a double black diamond run in the Chair 4 terrain pod - the same day ski patrol had conducted avalanche mitigation work on the slope.

Three bystanders and a patroller responded immediately to the scene. Following the rescue, patrol conducted an extensive search of the debris field but found no additional victims. The resort then closed terrain across the mountain for further avalanche control work before gradually reopening runs throughout the weekend.

What makes this incident noteworthy isn't just that inbounds avalanches are relatively rare at North American resorts - it's that Silver Mountain has form. In 2020, an inbounds slide on Wardner Peak killed three people. The resort's response was to permanently close a portion of that terrain.

The fact that patrol had already performed avalanche mitigation on Moonshine earlier on Friday raises questions about snowpack assessment. After a mostly dry winter, recent snowfall created unstable conditions that apparently weren't fully addressed by morning control work. It's worth noting that even the best avalanche forecasting isn't foolproof, but two significant slides in five years at the same resort warrants scrutiny.

The avalanche occurred late in the day - 4:30pm on Friday the 13th, for what it's worth - following a week of snowfall after an extended dry spell. This weather pattern is textbook for creating weak layers in the snowpack. New snow loading onto a weak base is Avalanche Safety 101, and exactly the scenario that should trigger conservative terrain management.

Following the weekend's avalanche control work, wetter weather moved in and forced further terrain closures. The rapidly changing conditions highlight the challenges resorts face managing avalanche risk, though it doesn't explain why Moonshine was open in the first place given the apparent instability.

Silver Mountain, located in Kellogg, Idaho, started life in 1967 as Jackass Ski Bowl - a name that at least had character. Originally accessed via a steep, difficult road, the resort installed North America's longest gondola in 1990, which remains its signature feature. The gondola transformed access to the mountain and allowed the resort to develop the base area in what was then a declining mining town dealing with Superfund site designation.

The resort has since expanded into a year-round operation with golf, hotels, an indoor water park, and the usual resort village infrastructure. It's a mid-sized operation serving the Idaho Panhandle market, not competing with the big destination resorts but offering decent expert terrain for locals.

This incident serves as a reminder that inbounds doesn't mean risk-free, even after patrol has signed off on terrain. The two skiers were fortunate - they had immediate assistance and walked away without serious injuries. But the pattern at Silver Mountain suggests either challenging terrain to manage or gaps in risk assessment.

The permanent closure of Wardner Peak terrain following the 2020 fatalities indicates Silver Mountain recognised it couldn't adequately manage risk in that area. Whether Moonshine or other expert terrain requires similar reassessment remains to be seen. At minimum, this latest slide should prompt a thorough review of avalanche forecasting and mitigation protocols - particularly on days when recent snowfall follows extended dry periods.

Resorts operate under significant pressure to keep terrain open, especially expert runs that define their reputation. But three deaths in 2020 and another close call in 2026 suggests Silver Mountain might need to err further on the side of caution, even if it means disappointing skiers and riders on powder days.

An aerial tram carrying around fifty passengers struck the boom of a construction crane on the route to Pic Blanc at Alpe d'Huez on Wednesday morning, injuring 23 people, three seriously. The cabin tipped on impact before the operator reversed it to right the car. Most of the injured were treated on site, with five taken to hospital in Grenoble, including a pregnant woman assessed as a precaution.

Why Glaciers Are Collapsing - And What Happens When They Do

Why Glaciers Are Collapsing - And What Happens When They Do

A deadly flood on the Nepal-China border, a decade-old tragedy on Italy's Marmolada, and an unstable glacier right now above a village near Zermatt - three very different mountain ranges, the same underlying story. Warming ice is destabilising terrain that was considered settled for generations, and the results range from catastrophic floods to slow-motion monitoring situations that could go either way.

Pitztal Glacier Set to Reopen for the 2026/27 Ski Season on 26 September

Pitztal Glacier Set to Reopen for the 2026/27 Ski Season on 26 September

Tyrol's highest ski area is gearing up to open a full month ahead of most of the Alps. The Pitztal Glacier is scheduled to start its 2026/27 season on Saturday 26 September, running through to 2 May 2027, with the lower-altitude Rifflsee area following in December. High-altitude terrain up to 3,440 metres gives the glacier a head start on snow, though as always, the actual opening extent will depend on how September's weather plays out. Early online ski pass bookings can save up to 30%.

Unstable Glacier Above Randa Puts Zermatt-Area Village on Alert

Unstable Glacier Above Randa Puts Zermatt-Area Village on Alert

A hanging glacier above the Swiss village of Randa, just south of Zermatt, has been shedding large chunks of ice for weeks, with authorities warning more break-offs are likely. A danger zone has been closed off since June, though officials say the village's 479 residents aren't at risk. It's a familiar pattern for this glacier - it's done this before, in 1819, 1972 and 1973 - but a reminder of how closely Alpine authorities now watch terrain once considered stable.

Thredbo Is 'On the Table' as EVT Reviews Its Whole Business

Thredbo is officially 'on the table.' EVT Limited, owner of Australia's most decorated ski resort, has hired Rothschild & Co to review its entire corporate structure - and confirmed Thredbo isn't off limits, even as it books a stronger year of earnings. The resort's own valuation has nearly halved after a brutal 2026 season, and speculation is already running toward Vail Resorts, Alterra, or a New Zealand operator picking it up. Here's what EVT actually said, and who could buy it.

Ski-E-O! Is the Ski Resort Tycoon Game We Didn't Know We Needed

I'm not a gamer. I'm a skier and snowboarder who happens to have a laptop. So when a ski resort management game called Ski-E-O! landed on Steam, I wasn't expecting to lose an afternoon to it - but here we are. Real mountain terrain, a full weather system, storms that roll in and wreck your snow base, avalanche danger, and enough depth to make RollerCoaster Tycoon feel simple by comparison. Early access lands in November. Here's what a few hours in the free demo actually looks like.

Sugar Bowl, California, Rebuilds Its Historic Village Gondola

Sugar Bowl, California, Rebuilds Its Historic Village Gondola

The rumours are true: Sugar Bowl is tearing out its Emerald gondola, in place since 1983, and replacing it with a new 8-person Doppelmayr system - nearly doubling uphill capacity to 1,800 people an hour. It's the fourth generation of a gondola line that dates back to 1953, when Sugar Bowl became the first resort on the West Coast to run one at all, and it's just one piece of a $100 million overhaul touching lodges, parking and snowmaking. Here's what's changing, and what's staying the same.

Two Confirmed Dead as Search Continues After Swiss Alps Fire

The death toll from Thursday night's fire at Restaurant Beverin in Thusis, Switzerland, has begun to firm up. One Swiss outlet, citing Graubünden Cantonal Police, reports that two of the five people initially reported missing have now been confirmed dead, leaving three unaccounted for. The building's collapsed stairwell and structural instability have slowed recovery efforts throughout. Here's what's changed since the fire broke out, and what's still unconfirmed.
