Mammoth Mountain's Ski Season Is Still Going Strong

How Is The Snow at Mammoth?

Mammoth's base is almost higher than Palisades Tahoe's Granite Chief Peak, which typically keeps temps much cooler, but you never know what Mother Nature will throw at you in late-May/early-June.

Despite temperatures creeping into the mid-60s and even low-70s at the base, Mammoth does a fantastic job of grooming and preparing its snow surfaces for optimal enjoyment. How? You might ask. The answer is salt, and lots of it.

Throwing salt over slushy snow raises the surface's melting point, thus allowing a thin layer of ice to form. When a skier passes over this layer, the ice and slush combo provides a fast-enough, and grippy-enough, surface to really let it fly. Instead of feeling sticky, the snow is smooth and edge-able. It's a fantastic feeling to lay down real carves on the first day of June.

How Many Runs is Mammoth Salting?

Mammoth doesn't salt every run each night, but I found fast and fun surfaces all over the mountain. The best example is the late-season race course that Mammoth reserves for athletes near Chair 23. The mountain had the course roped off for athlete training until about 11 a.m. each day, but when it opened to the public, it was a real treat. I found myself skiing fast, charging hard, and smiling from ear to ear.

On Sunday, June 1, 2025, my friends and I were feeling inspired to attempt a small pond skim adjacent to Mammoth's Chair 23. It was warmer on Sunday, however, and the race course was getting a tad sticky if you didn't stick to the salted areas.

So, naturally, we decided to tuck the entire race course in order to gain enough speed to slide across the small pond. Tap or click to watch the video of our pond skim below.

What Does Mammoth Have Open?

The snow is certainly melting at Mammoth, but the resort is holding on strong with its variety of terrain.

The Panorama Gondola was closed for the weekend to prep for summer mountain biking, but most of the mountain's terrain that's accessible from the Main Lodge is covered in snow and skiing well.

Mammoth had two Unbound terrain parks open on Saturday, but was forced to close the smaller rail and jump line for the season on Sunday due to rapid snowmelt. As of Sunday, June 1, there was a difficult rail and jib park, a large halfpipe, and one big jump still open to the public.

I personally could have spent the entire weekend lapping Chair 23. The snow is deep, and while a few rocks are beginning to poke through, I found comfort in skiing the steeps of Dropout and Whiteout Chutes on either side of the Chair. The snow was soft, but not too heavy. The slush bumpin' spring vibes were immaculate.

Further down Chair 23 is the nicely-formed Wiggle that was featured in the video earlier in this article. My friends and I took at least a dozen laps through this skier and rider-made course after sampling Chair 23's steeper terrain higher up.

Chair 2, also known as Stump Alley, was stilling running this past weekend, but the snowpack is getting very thin. Keep an eye out for updates from Mammoth as I would expect this zone to close sooner rather than later.

Face Lift (Chair 3) is also running. Saddle Bowl is perhaps in the best shape of all of Mammoth's groomed terrain. I enjoyed taking Chair 1 to Chair 3 for a near-top-to-bottom groomer laps. I would recommend getting there early for the best snow conditions. Who knows. You might even find fresh corduroy in June!

When Does Mammoth Close for the Season?

Mammoth intends to remain open for daily skiing and riding through Sunday, June 15, 2025. I would expect the operational footprint to gradually shrink as snow continues to melt, but Chair 23, Cornice Bowl, Saddle Bowl, and the World Cup race course should ski well to the very end.

Is It Worth Skiing Mammoth This June?

Yes. Go skiing. It's always worth it!
