More detailed information about the avalanche: 

Toured up to just below the ridge in Mammoth Rock Bowl. Variable snow to say the least. Definitely more of a fitness tour than getting any good skiing. Winds had their way with the snow all the way up. Winds were moderate with a few strong gusts from the west and northwest. 

Hand pits had the new 2-4" of snow breaking off easily. Kicked off a couple of tiny 3' x 3' wind slabs above 9400' on kickturns on the way up and on a few isolated turns in specific features on the way down.

Spotted this little wind slab that popped just off the ridgeline, most likely during the storm on Monday. 15' x 30' crown depth looked to be about 6-8" 

Only hit a couple of rocks :)
