Experienced cracking and collapsing on ridge up

to Wilson Peak. Performed belayed ski cut on the northern most chute of Wilson to see if we could get anything to move. Slope produced shooting cracks but did not move. Skied two laps into Wilson Glades without incident. For third lap, headed further N down ridge before dropping into the open slope above the pines. Slight change in aspect, slope angle and transition from concave slope to convex slope was enough to produce a slab avalanche. First skier down the slope triggered it and was able to ski off to the skiers right. Crown of slide was roughly 18" failing on facets. 50' wide. Running 200-300' down into the pines. Slope angle 33.
