While you're at Big Sky ski the Moonlight run under the Challenger chair. Not the super deep Volkswagen Bug sized moguls but big soft challenging bumps. After you've mastered that try Liberty Bowl off of the Tram. I'll bet on any given day on almost any mountain in the west it's easier to find good moguls than it is good powder.
There is so much ungroomed terrain at Alta and Snowbird that there can be plenty of bumped up areas. Of course, all it takes is one halfway decent storm (which happens a lot there) to bury them. Nobody goes to Utah to ski bumps though. There are no seeded bump runs like we have in the east, it would be impossible to keep them that way.
I believe these are courses for mogul comps. Some places they do it with the groomer to get the bumps started and then finish them off with hand tools. Some places they just have a mogul team go out and ski the same line continuously until bumps form. Then build in the jumps by hand.

No, those aren't hay bales under the bumps.
They're magnets. This is why anytime you're just exploring a resort and taking random trails just to see where they go you always wind up in a mogul field. Your metal edges are attracted to the magnets and before you know it you're on a bump run. Ever wonder why you never see people on XC gear in the moguls? Well, there's no metal edges to attract them there.
It also explains why it takes so much poise and concentration to ski the zipper line. The magnets are constantly pulling you towards the nearest mound.
