I can shed some light on that. There was one evening after a day at Alta where the canyon road was closed for a few hours, then it took nearly two hours to drive down the canyon once it was open. And there was another powder day where the canyon was closed in the morning, and traffic was heavy. (That day I waited until traffic cleared, and went up around 10:00 I think.)KingGrump- I went to the gathering thread from last season and didn't see what you were referring to.
If you arrived very early (like an hour or more ahead of lifts opening, driving and parking on the other days was fine. But some folks who showed up later did hit some traffic delays on other days as well.
Steamboat gets great snow... just not quite as much or as often as Snowbird. So they're not far off of each other. So yes, it could be as good or better. But playing the odds says Snowbird would be better. I think that's borne out in the graphs above, where Snowbird is about 10 points ahead of Steamboat - not a huge difference.Steamboat snow could be similar or better at Snowbird? That's the opposite from what everyone else has been saying.
