Vermilion crossing burn block ski

-14 deg at the car at the start of the day, 0 at the end but not enough sun effect to impact the E-NE aspect slopes we rode. The group ahead of us reached the ridge line ~1950m just before us and said as they stepped off the ski track onto the east side/sheltered side of the ridge to transition the entire ridge settled with shooting cracks both directions (north/south), travelling along the convexity. It didn't slide but the cracks went at least 30m either direction as as far as we could see. The skin track had been travelled on/broken in by at least 8 others probably from the day before judging by the old tracks. We didn't see another other shooting or any whumpfs further away from the ridge, except for one in gentle slopes ~1400m. Skiing was good and dead fall was well filled in but crust underneath began to feel more apparent ~1600m.
