I don't know about that particular area. I know about some runs, though. There's a run called George's Thumb at Breck. On powder days, there are people who stick to the rope line, people who know the route between the sharkfins, and people who are either lucky, or not. Maybe you got lucky on a known sharkfin route?
Full disclosure: The entire ridge is a sharkfin route, which is why everyone should stick to 1, 2, and 6 on blue bird powder days, and let me hit everything on the ridge first to make sure it's safe for others.
Have I posted this yet? A little misadventure on Patrol Bowl from a few years ago...
The music is what sets it apart. Nicely done.
