    Mammoth Mountain Prolongs Ski Season Until Mid-June

    Mammoth Mountain, a prominent ski resort in California, has declared June 15 as its official closing date for the 2024-2025 winter season. This announcement extends the skiing and riding season well beyond the typical closure dates of most Western U.S. ski resorts. The decision to remain open stems from the resort's substantial snowpack and continued interest from skiers and riders.

    The resort plans to maintain daily operations until the mid-June closure, with lifts running from 7:30 a.m. to 1:00 p.m. This schedule allows visitors to take advantage of the best snow conditions during the early morning hours, as temperatures tend to rise throughout the day. The extended season at Mammoth Mountain is a result of above-average snowfall in California's Sierra Nevada region this winter.

    Mammoth's ability to offer skiing into June is largely due to its high-elevation terrain, which helps preserve snow coverage even as temperatures increase. This late-season skiing opportunity has become a hallmark of Mammoth Mountain, setting it apart from many other ski resorts in North America that typically close in April or early May.

    The June 15 closing date provides skiers and riders with a final chance to enjoy snow sports before the transition to summer activities. After the ski season concludes, Mammoth Mountain will shift its focus to warm-weather pursuits such as mountain biking and hiking, as well as various summer events.

    Mammoth Mountain is located in the eastern Sierra Nevada of California, offering a diverse range of terrain suitable for all skill levels. The resort's high base elevation of 2,424 metres (7,953 feet) and summit elevation of 3,369 metres (11,053 feet) contribute to its reliable snow conditions and ability to extend operations into late spring and early summer. With 3,500 acres of skiable terrain and an average annual snowfall of over 10 metres (400 inches), Mammoth Mountain continues to be a popular destination for late-season skiing in the Western United States.

    Arosa to Replace 40-Year-Old Hörnli Lifts With New Gondola and Chair

    Arosa to Replace 40-Year-Old Hörnli Lifts With New Gondola and Chair

    Arosa's Hörnli sector is getting its biggest overhaul in decades. The 1986 gondola and 1994 chairlift linking toward Lenzerheide are both being replaced, with capacity up, tower count down and a new base station lower on the hill. At roughly CHF 67 million, it is the largest single investment Arosa Bergbahnen has ever made - and the target opening has already slipped a year, to December 2028. Here is what is changing, and why the timeline moved.

    Sundance Mountain Resort Is Getting a New High-Speed Quad and More Back Mountain Terrain This Winter

    Sundance Mountain Resort Is Getting a New High-Speed Quad and More Back Mountain Terrain This Winter

    Sundance Mountain Resort's back mountain is finally getting a proper lift. The Electric Horseman Express opens for 2026-27, unlocking a new bowl next to Bishop's Bowl and three expert gladed chutes across roughly 105 fresh acres - on top of the Storyteller ridge run that debuted in preview form last season. It's Sundance's biggest expansion since 1985, and it turns a three-lift slog into a single six-minute ride to Bearclaw Summit.

    Levi and Ruka Confirm October 2 Opening on Farmed Summer Snow

    Levi and Ruka Confirm October 2 Opening on Farmed Summer Snow

    Finland's Levi and Ruka open for the 2026-27 season on October 2, more than seven weeks before most of Europe sees a lift turn. Neither resort is waiting on autumn snowfall - both are skiing on snow buried since last spring, insulated through the Finnish summer and dug back out for opening day. It is not a shortcut. It is a decades-old system now spreading from the Arctic Circle to Idaho, Utah, Vermont and Colorado. Here is how snow farming actually works, and why it is catching on.

    Sölden's Old Einzeiger Chairlift Gets a Second Life in Montafon

    Sölden's Old Einzeiger Chairlift Gets a Second Life in Montafon

    Silvretta Montafon is replacing its ageing Freda chairlift - but not with something new. The resort is having a 1999 four-seater chairlift, retired from Sölden, dismantled, shipped to Vorarlberg and rebuilt with new electronics, cable and clamps. It has to be running before March 2027, when Silvretta Montafon hosts the FIS Snowboard, Freestyle and Freeski World Championships - the biggest winter sports event Vorarlberg has staged. Here's how a reused lift ends up cheaper.

    Nassfeld Invests €13 Million in New 6-Seater Chairlift for 2026/27 Season

    Nassfeld Invests €13 Million in New 6-Seater Chairlift for 2026/27 Season

    Nassfeld is putting €13 million into a new 6-seater chairlift, the Tressdorfer Almbahn, connecting Sonnleitn with the Tressdorfer Alm from December 2026. It replaces three ageing drag lifts and will run through summer too, from June 2027, moving up to 2,500 people an hour on the roughly three-minute ride. It's the latest step in Carinthia's largest ski resort building out a genuine year-round offering, following last year's Gartnerkofelbahn gondola.

    Stelvio Glacier Suspends Summer Skiing, Leaving Continental Europe Without a Lift-Served Slope

    Stelvio Glacier Suspends Summer Skiing, Leaving Continental Europe Without a Lift-Served Slope

    Italy's Stelvio Glacier has pulled the plug on summer skiing from August 15. It was the last lift-served ski option left standing in continental Europe, and now there's none. Operator SIFAS pointed to persistent heat, storms, and a snowpack that simply wasn't refreezing overnight anymore. The cable car keeps running. Whether skiing comes back later this summer depends on the weather turning - and right now, nobody's promising anything.

    Maverick Mountain's Only Chairlift Destroyed as Sand Creek Fire Tears Through Montana Ski Area

    Maverick Mountain's Only Chairlift Destroyed as Sand Creek Fire Tears Through Montana Ski Area

    Firefighters saved every base building at Maverick Mountain, Montana, but the resort's sole chairlift didn't survive the Sand Creek Fire. Owners Erik and Kristi Borge say the lift is "most likely" out for the 2026/27 season after flames tore through the mountain on August 8. The wildfire has since grown past 27,700 acres with zero percent containment. It's a gutting result for the tiny, one-lift operation near Dillon - though the lodge, groomers and equipment all made it through untouched.

    Fairmont Niseko: New Luxury Resort Revives Stalled La Plume Site for Early 2028 Opening

    Fairmont Niseko: New Luxury Resort Revives Stalled La Plume Site for Early 2028 Opening

    Fairmont is bringing its second Japanese property to Niseko, and this one's got history. The 165-room resort will rise on the site of the stalled La Plume project, which collapsed into bankruptcy in 2025 before J-Will Partners bought the site for redevelopment. Set between Mount Yotei and Mount Annupuri, it's slated for an early 2028 opening - putting it in play for the 2027/28 season. Expect two restaurants, a spa, onsen bathing, and a kids' club, a short drive from Niseko Village and Hirafu.
