The crown covers a bunch of the ridge dividing the primrose overlook from UFO 1. We didn't want to get close given the location of the side and what it would take to get there. It appeared to slide on the new/old interface and run a long way on the low angle south east facing corner.

Skiing the north east slope, about 4 turns in I saw a large crack below me. It appeared to be in the storm snow. It's not steep enough to slide but had it been steeper it would have.

photo 1 - the slide on the ridge. The crown runs up and down both sides of it. Behind the trees is UFO 1.
