There is no shortage of mogul (bump) runs at Big Sky Resort. One thing I like about Big Sky is that not all of the mogul runs are super steep and nasty. Bumps runs at Big Sky range from very steep to moderately steep to almost an lower intermediate level grade. Because of the wide variety of bump runs, Big Sky is a superb place to learn how to ski the moguls for those whose skill level isn't up to competing in the Olympics.
