Some resorts have a different visions on what they want their mountain to look like.
For example, Sun Valley, who owns Snowbasin, mainly ALL their park features (including but not limited to huge ass jumps, a world class super pipe, as well as a progressive park and skier/boarder cross course) is located on Dollar Mountain, which is separate from the "main" mountain. Baldy (the main mountain) is an excellent mountain offering wide open bowls, excellent glade skiing off the backside, and not limited to arguable they highest quality corduroy offered in the west. Prior to the moving of many park features to Dollar, the pipe and smaller park features were located on Baldy.
For me, this proves to the fact that some resort companies have a different vision on what they want THEIR mountain to look like.
