we open on the 19th last year...but we didn't hit our 100 in. untill mid dec... so it's entirely possiable. I've seen it open on oct.30 before...so i'll keep doing snow dances. but if your at alta before a 100 in. expect to take a few core shots. the wasatch granite is hard.
have you ever even been to alta. Cause alta is like the worlds best resort, and the regular snows that dump truck loads of snow almost every week is the icing on the top.
