Mammoth Mountain Snow Report 5-7-2021

Mammoth Mountain Snow Report 5-7-2021 It’s been a fun week of spring skiing and snowboard out on Mammoth Mountain. The first part of the week was a bit warm but it’s cooled off now and the snow is getting much better. 

Checking in on the snow base at the snow study site at 9000 feet we are down to 1 inch of snow. Let’s remember that this is natural snow, there is no snowmaking that took place at the snow study site, so it can go down to dirt while there is still skiing and riding down to Main Lodge.

Out on the runs, I would say there is a good 2-5 feet from Main Lodge to the Top. Crews have been pushing snow around and will continue to do so to keep Mammoth open for 3 more weeks. 

My bet is by the end of the season Broadway will be down to a ribbon of snow with everything else pretty much melted out that feeds into Main Lodge. 

Grooming continues like normal out of Main Lodge with both Scotties and Cornice up top getting groomed nightly. All the lower runs are groomed out nightly and when it warms up they turn into a nice soft buttery surface. 

Up Top Wipe Out 1 has been the winner this week with enough traffic to make the snow into nice spring slush. By noon once you get out of the upper section it has been getting a bit slow. Some of this snow is still trying to convert back to spring from the snow we got 10 days ago. 

Climax is fun, also try Sign Line for the best snow of G2, and of course, Cornice is good with some fun corn and slush.

The Unbound Parks are still fully built out and will be good to go for at least a couple more weeks if not longer. I will get some fresh photos and video of what’s set up next time I am on the hill.

Lift hours this week will be 7:30 to 2 PM with chairs 1, 2, 3, 6, 11, and 23 along with G1 and G2. During the mid-week chairs, 5 and 10 will not be open, but they look to run those lifts this Friday – Sunday.

If you’re going to be out on the hill the next few weeks you need to wax daily or you’re going to stick badly in the spring snow. Unless you like hard snow I would avoid the 7:30 start, for those who like it fast and firm have at it. To those who like the snow soft, an 8:30 to 9 AM start is going to be best this weekend. 

FYI: if you wax up and go out early in the hard snow most of that wax is going to rub off before you really need it. Early birds I would have a pair of skis or a board for early starts and then switch over to a fresh set up after 9 am with yellow wax when it’s really starting to get wet out there.
