Counting the couloirs or gullies of the ridge from east to west, this appeared to be the fourth (hence "#4"). It has a somewhat disconcerting roll-over at the top, which is a great way to inspire some conversations about everyone's comfort level and the utmost trust in the snow conditions.
That said, as opposed to some of the other ski options, this couloir can be scouted from top to bottom without any cliff bands or obstacles and a long run out at the lake, in case the worst happens. There is good potential here to do another lap or to try another of the neighboring couloirs.
We were able to continue the traverse back to the approach all the way back to the car without having to transition and with minor skate skiing.
