This mountain has any kind of skiing anyone could want; steep(VERY), trees, open bowls, chutes, LOTS of blue and green runs. Two chair lift rides will get you to almost anyplace on the mountain with most now being high speed detachable chairs. Not many lift lines anymore, because of the high speed chairs, but you can go up to the top of the mountain to get away from crowds. I don't ski in the terrain parks but there are at least 2 top quality ones. Eating on the mountain is expensive but there are a lot of good choices.
I have skied Europe, South America, Canada, our Rockies, etc., and Mammoth Mountain is still my favorite.
