If it's coming off Blackcomb peak, I think I know where it is. It would involve about a 45 minute hike. There is plenty of terrain that are not designated runs. If you're goofy enough to ski them, fine. Keep in mind that if you ski out of bounds and need assistance, you pay for it. Helicopter time for the AStar is about $1000/hr, equipped rescue techs about $80/hr each, and an ambulance ride to Squamish hospital about $800, most of which is not covered by many travel medical plans. Skiing a closed area in-bounds will lose you your ticket, a real drag if you just bought a 5 day pass.
In other words, you shouldn't just blindly head out to make your own line. There is terrain up here that can kill you. Scope out the line you want to head for by studying it from several angles, check the snow conditions carefully, talk to locals on-site. There is no shame in bugging out, even if it means quite an uphill climb; better to be a live chicken than a dead duck. I'm no expert, but have watched plenty of people bite off more than they can chew. If you're an American, keep in mind that it's tough sue in Canada for injuries brought on by your own stupidity.
So much for the sermon. Now if you really think you can ski it, GO GET IT!
