> Is that to early or what?
gosh no! anytime after december 1st is good. last year i skied early December with only 38" base reported and the skiing was great!
what do you mean by getting into the backcountry? there is tons and tons of inbounds by yourself skiing. backcoutnry is available, but personally i think that is better left for the locals, just because there is so much awesome inbound to explore during the few short days of a ski trip.
What I don't like about March is if it doesn't snow and the weather isn't right, the snow turns bad quick, also, because there is more a daytime thaw nighttime freeze cycle, that tends to make the moguls steeper and stiffer than in dark winter. this is only if it doesn't snow. but, certainly anytime from december through april is a good shot for utah. march also brings spring break and i think more crowds than feb, except for pres day.
