More detailed information about the avalanche: 

After a ski up towards Red Cone and back down the skiiner we poked in to the top of Twin Falls. On the first steep roll over we found a 1F hard wind slab, I put a ski cut in and cut loose a Small slide that propogated 40' wide and ran 80'. Crown Height was an average of 1' and at it's steepest this section of the falls was 39˚. The snow failed 25cm down on loose unconsolidated stellars and decomposing rods that was F hard.
