 Comments: Large slide propagated from a skier. Skier was on a 25 degree west ridgeline. Slide released 30 ft to the left of skier where the slope rolls off to the SW at 37 degrees, crown wall 20" to 30", 500 ft wide, may have run for 1,000 ft., heard sound of trees snapping, large snow cloud. May have propagated across ridge lines to the left and uphill for up to 1/4 mile and 500 ft. higher. Saw other crown walls from below and thought that may have run all from the original release. Not verified. Gut feeling before skiing was slope was loaded and ready to go,
