Snowbasin rocks! The terrain there is amazing, especially if your willing to explore around and look. (i.e. backcountry) The park is pretty cool too. Not exactly Park City, but they have some pretty sweet rails and jumps. Oh yeah, they've got Utah's only teeter-totter rail.
Snowbasin is all about timing catch it on a good day and it rocks on a bad day all ice. Also it is a ways out of Salt Lake and doesn't get as much snow as the little and Big canyon resorts. Park is ok but no reason to ride it out there, ride the olympic gondola looks like a coke can acesses some hard core shit
