The End of an Era...We are Shutting Down the Messageboard

The messageboard is now in read-only mode and no new posts or topics can be created. We will leave the messageboard up for historical purposes, but you will not be able to make new posts or comment on existing ones.

We have started a Discord server and hope that you all will join us on there. Technology has changed over the years and maintaining the messageboard has become somewhat of a pain in the butt and Discord offers many features for users, the main one being a very polished mobile app.

We really hope you all will join us on Discord and think you will like the platform. Use the invite link below to join.

Mammoth Mtn 306in of snow: 12-14 feet base (144-168in)



Snowbird 336in snow: 10.5 feet mid-mountain (127in)



Big Sky 280+in snow: 4.75-7.33ft (57in-88in)



Vail 299in snow: 5.67ft mid-mountain (68in)



Now the break down for the snowfalls is different for a lot of the resorts, but you can look into that for yourself at that stuff.

Cumulative snowfall does not equal base depth.

Amazingly enough that stuff packs down, I don't recall seeing an example of that this weekend but I hear it does.

:oops: Right, right...I get that :-). I'm mostly refering to Mammoth's base depth (because I'm heading there in mid-March). Mammoth is boasting the deepest bases in the country yet the BIG snowfall they had was like a month ago and they've seen day time temps in the 40s quite a few days.



The other resorts pretty much speak for themselves.

And...think about Big Sky's base depths. It's nearly half that of the other resorts...but it sure hasn't seen half the snow totals as the other resorts :? .

Base depths depend on a lot of variables, because of its moisture content Mammoth's snow makes a more substantial base than say Utah snow given the same amount of snowfall. Put another way, the wetter the snow the better base it compacts to and the closer the base depth will equal the snowfall depth. Drier snow compacts much more than wet snow, so in a drier snow environment it will take more snowfall to compact into a base. Wind, temperature, and skier traffic are also variables that affect base depth vs snowfall.

Right on TD. Water content has everything to do with the base depths. Mammoth gets the heavier snow, so their snow packs a lot thicker than the snow in CO and UT.



The other thing to think about is the terrain the snow is covering... in CO, a 50-60 inch base is more than enough. In UT, it might require a 80-90 inch to cover their terrain.
