The Overview

Mammoth Mountain spans 3,500 acres across California's Eastern Sierra with a summit at 3,369 metres and a base at 2,424 metres, delivering 945 metres of vertical drop. The resort operates 180 named runs distributed across 15% beginner, 48% intermediate, 24% advanced and 13% expert terrain. Annual snowfall averages 10.16 metres at the base, rising above 400 inches at upper elevations where the summit reaches 11,053 feet. The 2022-23 season recorded over 700 inches at Main Lodge, marking the snowiest winter on record.
The mountain's 65% north-facing aspect ensures reliable snow preservation from November into June, with terrain spreading horizontally across four distinct base areas. Chair 23 accesses steep chutes and exposed upper bowls above treeline, whilst Chair 22 serves wind-sheltered expert runs including the Avalanche Chutes on Lincoln Mountain. The Panorama Gondola reaches the summit in seven minutes, connecting to Cornice Bowl and advanced alpine terrain. Unbound Main Park anchors a terrain park system comprising 10 parks, two halfpipes, over 100 jibs and 50 jumps across 100 acres.
Main Lodge sits at 2,743 metres and serves as the historic hub, whilst Canyon Lodge and Eagle Lodge provide family-oriented beginner zones with dedicated learning areas. The Village at Mammoth connects to Canyon Lodge via a 15-passenger gondola, creating pedestrian access between lodging and slopes. Weekends draw crowds from Los Angeles and Southern California, though the resort's sprawling layout disperses skiers efficiently. Wind frequently closes upper lifts during storms, sending advanced riders to the protected Chair 22 zone.
Mammoth is included on both the Ikon Pass with unlimited access and the Mountain Collective with two days. The 2025-26 season opened 14 November and runs through 25 May, with extensions possible into June or July during heavy snow years. The resort attracts Olympic athletes training in its world-class terrain parks and suits intermediates seeking long groomed runs, experts chasing steep lines, and families requiring varied terrain. Altitude, massive acreage and exceptional park infrastructure define the Mammoth experience.

When to visit Mammoth Mountain
The 2025-26 season opened 20 November following snowmaking preparation and runs through 25 May 2026, with daily lift operations from 7:30am to 2:00pm during spring hours beginning in May. Mammoth typically operates from early November into June, with exceptional years extending into July or August. The 1994-95 season opened 8 October and closed 13 August, whilst 2017 closed 6 August and 2022-23 ran until 6 August following record snowfall. Season length averages over 200 days.
Annual snowfall averages 400 inches at base elevations, exceeding 10 metres total accumulation and rising past 500 inches at the 11,053-foot summit. The 2022-23 winter delivered over 700 inches at Main Lodge and nearly 900 inches at the summit. February and March historically produce the heaviest snowfall, with the first week of March averaging 43 centimetres. November typically receives 32 inches, whilst December through February each deliver 67 to 71 inches. Snowmaking covers 33% of terrain, establishing a reliable early-season base.
January and February offer peak powder conditions, whilst March balances fresh snow with increasing sunshine. April and May deliver spring corn snow under bluebird skies, with temperatures rising but coverage holding at altitude. The resort benefits from 300 days of annual sunshine. The 2025-26 season received 87 inches in February alone, securing a Memorial Day closing despite a slower early winter. Mammoth's east-side Sierra location captures Pacific storms whilst the 2,424-metre base elevation prevents rain.
Night of Lights returns 14 December annually at Canyon Lodge with fireworks and family activities. Elevation Mammoth gay ski week runs 12-16 March 2025. Ikon Pass holders receive Early Ups exclusive morning access on select dates with complimentary breakfast at McCoy Station. The resort does not offer night skiing but extends spring hours to maximise morning corn snow. Chair 1 banner breakthrough and opening day ceremonies feature Woolly the mascot and complimentary beverages.

Getting there
Getting to Mammoth Mountain, and where to stay
Mammoth Mountain rises from the eastern slope of California's Sierra Nevada range in Mono County, 58 kilometres southwest of the Nevada state line. The resort sits above the town of Mammoth Lakes at 2,424 metres base elevation, surrounded by the Inyo National Forest and Long Valley Caldera volcanic landscape. The summit reaches 11,053 feet, making Mammoth California's highest lift-served ski area. Volcanic geology defines the terrain, with the mountain itself a lava dome complex.
Mammoth Lakes town lies 6.4 kilometres from Main Lodge along Highway 203, offering lodging, dining and services for a resort community. The Village at Mammoth provides slopeside accommodation, restaurants and pedestrian access via gondola to Canyon Lodge. Los Angeles sits 307 miles south via US 395, Reno 168 miles north, and San Francisco 360 miles west during winter when Tioga Pass through Yosemite closes seasonally. Highway 395 runs north-south through the Eastern Sierra, providing primary access.
The drive from Los Angeles takes five hours via Interstate 14 north to Highway 395, passing through the Owens Valley with views of the White Mountains and Ancient Bristlecone Pine Forest. From Reno the journey requires three hours south on US 395, passing Mono Lake and the ghost town of Bodie State Historic Park. San Francisco requires six to seven hours in winter via Highway 99 or Interstate 5 east, then Highway 395 south, as Tioga Pass closes from approximately October through May.
Mammoth Yosemite Airport sits 10 minutes east on Highway 395 with seasonal United Airlines service from Los Angeles, San Francisco and Denver, plus Advanced Air from Carlsbad and Hawthorne. Eastern Sierra Regional Airport in Bishop operates 45 minutes south with year-round United flights from San Francisco and seasonal Denver service beginning December. Mammoth All Weather Shuttle, Mammoth Taxi and rental cars serve both airports. Eastern Sierra Transit Authority operates free shuttles between Reno Airport and Mammoth. Winter driving requires chains during storms.

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.

Selwyn Snow Resort Closes Early as Rain Ends Its 2026 Season
Selwyn Snow Resort has called an early end to its 2026 season, a day after Victoria's Mount Baw Baw did the same. Rain on Thursday stripped what was left of the snowpack, and the cold nights needed to rebuild it through snowmaking never arrived. It's a rough result for a resort that only just found its footing again after being burned to the ground in the 2019-20 Black Summer bushfires and a multi-year rebuild. Here's how the season fell apart, and where Selwyn's been since the fire.

Mt Baw Baw Becomes First Australian Resort to Close for 2026
Mt Baw Baw is calling time on its 2026 season this Sunday at 5pm, becoming the first Australian resort to close for the year after warm spells and rain wore through its snowpack. Lifts stop, but the resort stays open, entry fees get waived, and there's one last Bollywood Weekend before the lights go out. Fifty-seven days after opening, here's how the season ended and what it means for the rest of Australia's struggling snowpack.

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'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
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
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 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.

Understanding the Mammoth Mountain snow report
Get the latest Mammoth Mountain snow report — real-time snowfall, snow depth, and mountain weather for this California resort, spanning 2424m to 3369m in elevation.
Snow measurements
Base depth, summit depth, and recent snowfall are the core numbers to watch. At Mammoth Mountain, summit conditions (3369m) can differ noticeably from the base, so we break both out separately rather than showing a single average.
Weather conditions
Current weather conditions affect snow quality. Cold temperatures with low wind typically preserve snow quality, while warm temperatures or rain can impact conditions negatively — something worth watching closely at Mammoth Mountain's 2424m base elevation, where temperatures run milder than the summit.
Data sources
Mammoth Mountain snow data is collected through a combination of on-mountain reports and weather forecasting services, giving you both official resort updates and independent forecast data in one place. The mountain is served by 31 lifts, including 9 quad chairlifts and 4 6-person chairlifts.
When to check
Snow reports are typically updated early morning and late afternoon. For the most current conditions, check back regularly, especially if a winter storm is approaching.
