Replying to A little Swiss need some help and info!!

 
Here is the deal , a friend and me have decide  to go skiing to  the states in march during our holiday's, so we would like to know where is the best place to go at this time of the year.

Here is what we are surching:


- Some ski resort where they are some fucking good and enormous snowparks ( really really big one ....lol).Some friend told me that the best place to go where Mammoth,keystone, and park city.

-Or some ski resort where they are some good snow conditions!(powder ? at this time of the year?)



Where do we have to go? Colorado? California?

Any suggestion??
