The Overview
Michael Fulton
Melbourne-based skier and snowboarder with 50+ resorts across 5 continents. Specialises in Australian resorts and international resort comparisons.
Lost Trail Powder Mountain's summit reaches 8,196 feet, dropping 1,795 vertical feet to a base at 6,401 feet across 69 runs spread over 1,800 acres straddling the Montana-Idaho border. Terrain splits 40 per cent intermediate, and 20 per cent each for beginner, advanced and expert, with average annual snowfall of roughly 306 inches. The resort carries Indy Pass affiliation. Eight lifts, including five double chairs, serve the mountain alongside three surface lifts.
Lost Trail sits at the junction of US Highway 93 and Montana State Highway 43 at Lost Trail Pass, with Chairlift 1 running approximately along the Idaho-Montana border and terrain to its south, including Chairlift 2, actually located in Idaho. This border-straddling geography, combined with the resort's legendary Thursday powder days, has built a devoted following among skiers in the Bitterroot Valley and beyond. The evenly balanced terrain split across all four ability levels suits a genuinely broad range of skiers.
The ski area traces its origins to 1938, when it began as a modest, volunteer-operated facility on the Continental Divide. The pass itself takes its name from a local rancher's insistence, informed by his familiarity with the Lewis and Clark journals, when US Highway 93 was built through the area in the 1930s. Ownership of the ski hill changed hands roughly every three years through its early decades until the Grasser family took over.
In 1967, local resident Bill Grasser and business partner Chuck Shuland acquired the property, with Grasser buying out his partner in 1975 after operating the resort together from 1969. The mountain is now owned by Scott and Judy Grasser, continuing more than half a century of family ownership. Adult daily tickets run from 45 to 55 US dollars.

When to visit Lost Trail Powder Mountain
The 2025-26 season at Lost Trail Powder Mountain ran from 5 December 2025 to 6 April 2026, a roughly eighteen-week season supported by average annual snowfall of around 306 inches. This substantial snowfall total underpins the resort's legendary reputation for deep, reliable powder, particularly on the Thursdays for which the mountain has become known among regional skiers.
Midwinter, from December through February, typically brings the most consistent conditions across the resort's evenly balanced terrain. Given the mountain's remote setting straddling the Montana-Idaho border at Lost Trail Pass, the resort draws primarily from the Bitterroot Valley and broader regional skier base rather than national destination traffic, keeping crowds notably lighter than more accessible resorts.
As an Indy Pass resort, Lost Trail draws some visiting skiers holding that multi-resort pass in addition to its core regional base. The resort's genuinely balanced terrain split across beginner, intermediate, advanced and expert skiing suits families and groups with mixed ability levels. School holiday periods bring increased family visitation given this broad terrain appeal.
Specific event programming beyond standard operations and the resort's Thursday powder day reputation is not confirmed in available resort information. More than fifty years of Grasser family ownership, from Bill Grasser's 1967 purchase through to the current Scott and Judy Grasser stewardship, continues to shape the resort's community-focused, family-run character each season. Lost Trail's unusual cross-border geography remains a distinctive point of interest for visitors throughout the winter.

Getting there
Getting to Lost Trail Powder Mountain, and where to stay
Lost Trail Powder Mountain sits at Lost Trail Pass, straddling the Montana-Idaho border at the junction of US Highway 93 and Montana State Highway 43, with a base elevation of 6,401 feet and a summit at 8,196 feet across a 1,795-foot vertical drop over 1,800 acres in the Bitterroot Range. This remote setting places the resort along one of the more scenic mountain passes in the northern Rockies.
The Bitterroot Valley, to the north in Montana, and the Salmon, Idaho area, to the south, both provide lodging and services within a reasonable drive of the resort. Missoula, the nearest larger city, lies a considerable distance north through the Bitterroot Valley. This remote location keeps the resort's visitor base genuinely regional rather than drawing from major metropolitan areas.
US Highway 93 provides direct access to Lost Trail Pass from both the Montana and Idaho sides, making the resort straightforward to reach despite its remote setting. Winter driving conditions on this mountain pass route can include snow and ice, and the substantial snowfall the area receives means chains or traction tyres are often advisable during storms. There is no direct public transport service to the resort.
Missoula International Airport, a considerable drive to the north, is the nearest airport with substantial commercial service. This distance reinforces Lost Trail's identity as a genuinely remote mountain destination reached deliberately by regional skiers rather than a convenient fly-in resort.

Mount Buller Becomes Latest Australian Resort to Call Time Early on 2026
Mount Buller closes out its 2026 season this Sunday, joining Falls Creek, Hotham and Charlotte Pass in a cluster of closures landing almost simultaneously and roughly a month ahead of schedule. The culprit is stark: Spencers Creek's benchmark snow depth hit 31.2cm on 3 September, just 18% of the 73-year average and an all-time low for this point in the season. Six of Victoria and NSW's best-known resorts will have shut their lifts early within a span of about two and a half weeks.

Tremblant to Add New Timber Summit Ski Sector for 2027/28 Season
Tremblant has confirmed a major expansion of its Quebec ski area, with a new Timber Summit sector adding 62 acres of terrain, eight trails and a high-speed quad chairlift for winter 2027/28. It's part of a CAD 42.5 million investment that also includes a new beginner learning zone at Versant Soleil opening this coming season. The project has grown considerably since it was first announced back in 2020, when it carried a far smaller budget and an opening date that never eventuated.

Mount Hotham to Close for the 2026 Season on Sunday, September 6
We knew when the Bird Bath Pond Skim showed up on Hotham's Instagram that the season was on its way out. It's been a rough one - I only managed two days on snow all year, at Falls Creek - and now Baw Baw, Selwyn and Hotham have all called it, possibly the worst Australian season I've seen in a decade. Hotham's last day of lift operations is Sunday, 6 September, with a Retro Day, Father's Day après and closing sales before the lifts stop turning for good.

Thredbo to Replace Ageing Gunbarrel Quad With New Six-Seat Chairlift for 2028
Thredbo Alpine Resort has confirmed plans to replace its 37-year-old Gunbarrel quad chairlift with a new six-seat Doppelmayr D-Line, targeting winter 2028. The AUD 35 million project will keep travel time roughly the same but lift capacity from 2,800 to 3,000 skiers per hour. It's part of a broader investment push that also includes doubled snowmaking capacity at Friday Flat for 2027, with the ageing Kosciuszko Express now flagged as the resort's next major lift replacement after Gunbarrel.

Aerial Tram Collides With Crane at Alpe d'Huez: 23 Injured
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
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
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
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.
