Say no to Crack

Riding south east facing slope approx 20 degrees where cracking is shown. Rider 1 went through and rolled over a convex slope triggering a small slide that propagated a few hundred feet that took the recent snow with it (approx 12-18” deep in the area). After rider 1 had gone, the other two riders noticed more cracking above on an approx 20 degree slope propagating as far as they could see. Riders exited the area immediately.
