As Christmas week arrives, winter is settling in across the Sierra in a meaningful way. After a slow and uneven start to the season, multiple storm systems are now delivering the kind of consistent snowfall resorts need to open terrain, spread skiers out, and build a more complete holiday experience.
In the Eastern Sierra, Mammoth Mountain continues to see heavy snowfall, with more than a foot piling up in short bursts and additional storms lined up. Crews are working continuously to dig out lifts, manage deep snow, and safely expand access as conditions allow. It’s a strong signal that Mammoth is heading into one of its most promising holiday periods in recent years.
Around Lake Tahoe, momentum is building resort by resort. Mt. Rose Ski Tahoe has opened new terrain and summit access during brief weather breaks, while Kirkwood Mountain Resort and Northstar California Resort are steadily adding lifts and zones as coverage improves. Sugar Bowl Resort and Heavenly Mountain Resort are also benefiting from the storm cycle, with opening days, tubing, and expanded lower-mountain options rolling out just in time for the holiday crowd.
Further south along the crest, Sierra-at-Tahoe is preparing for opening with forecasts calling for multiple feet of snow—exactly the kind of base-building storm that supports safer operations and broader access.
The story across the Sierra right now isn’t just snowfall totals—it’s capacity. More terrain, more lifts, better coverage, and safer conditions mean resorts can handle holiday crowds more comfortably while delivering the winter experience travelers have been waiting for.
If you’re heading to the mountains this Christmas, expect changing conditions, phased openings, and hardworking crews pushing through the storms to get more of the Sierra open. Give them time, respect rope lines, and ride within your limits.
Winter has arrived—and the Sierra is finally ready to share it.
