Crossover is another really bad excuse for a trail. Yes, it has to be there because it is a bailout from Willaimson. They have this trail there for one thing only, so that marketing can boast that more trails are open. It makes it so that Upper Williamson can be open and Lower Williamson doesn't have to be. To get to this trail go to the summit and ski down to the top of Upper Wingding and Upper Willaimson. Then ski Upper Williamson until you see the bailout. Crossover is very flat and you usually need to pole to get out of it. The only reason that I would ski this is as a bailout from Upper Williamson.
