avalanche broke on a suncrust(?) that was 2-3' deep. layer was not reactive in pit dug lower on slope. avalanche propagated fairly wide for the terrain, wrapping around a sub-ridge in the terrain

took a nice lap on west facing white pine, 1/2 mile or so upcanyon from fork in trail to red pine second lap, spooning tracks from previous run, slab broke on a small terrain rollover no wind loading, just slowly accumulating storm snow, added another two inches from our previous run slab broke 2-3 feet deep and moved quite a bit of snow into a grove of trees (would have been ugly) slab broke just above me, 90% of avalanche snow was below me entire time i managed to dig ski edges into bed surface to self-arrest before this group of trees airbag pack was deployed, i think this was very crucial in avoiding extended carry because it allowed me to not get pulled under, so i could dig ski edges and claw at bed surface as snow decended around me. i stopped above the trees, still on a steep slope, without injury cause is still a bit mysterious, no blatent red flags to the situation just too much fresh storm slab? sorry no pics thanks for all your diligent work uac!
