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.

FIS Weighs Holding World Championships in Almost Every Winter, Starting 2032
The International Ski and Snowboard Federation is looking at a major shake-up to its title events calendar. From 2032, World Championships could run not just in odd-numbered years but in every non-Olympic winter too, effectively putting a global title event on the calendar almost every season. The FIS Council has approved the concept following a feasibility study, though an accelerated rollout as early as 2028 is also under consideration.

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.

Lost Trail Powder Mountain Lift System
Lost Trail Powder Mountain runs eight lifts: five double chairs and three surface lifts, serving 69 runs across 1,800 acres straddling the Montana-Idaho border. Chairlift 1 runs approximately along the border itself, while terrain to its south, including Chairlift 2, sits across the line in Idaho, giving the resort a genuinely unusual cross-border lift configuration.
The lift network has developed since the resort's origins as a volunteer-operated facility in 1938, through decades of frequent ownership turnover before the Grasser family's long tenure began with Bill Grasser and Chuck Shuland's 1967 purchase. Grasser family ownership since then, now under Scott and Judy Grasser, has supported steady investment in the current five double chairs and three surface lifts.
The double chairs distribute skiers evenly across the resort's genuinely balanced terrain, spanning beginner through expert skiing in roughly equal proportions. The three surface lifts support beginner and learning areas near the base. There is no gondola, quad or high-speed chair, consistent with the resort's identity as a family-run, community-scale mountain.
Specific recent lift replacement or expansion projects beyond the current eight-lift network are not confirmed in available resort information. More than fifty years of continuous Grasser family ownership has supported steady, incremental investment in this cross-border lift network. The resort's Indy Pass affiliation brings additional visiting skiers to a lift network with a genuinely unique geographic footprint.
