u r wrong. alta is dope, especially with snow frequency and density. But... alta is not steep whatsoever besides the very top of baldy, and parts of eagle's nest. also, there are a ton of flat light days. even bc access isnt that great besides wolvy and rocky (gotta love a-frame). also, be extremely careful claiming the best in the WORLD. there are alot of mountains out there. europe lacks the tree skiing, buts thats about it.
to top things off, every skier is different, therefore certain criteria is more important to some than others. there wont be a concensus for this thread of the best resort.
steeps=jackson
snow=alta/grand targhee
park=mammoth, pc
crowds=solitude
bc access=jackson
weather=cali/co
travel ease=cottonwoods
area(amount of terrain)=whistler
stoke factor=squallywood/jackson
the pac. northwest, and sierras can get the most snow, but it's heavy, and seasons are inconsistent.
done and done.
