01/14/2016 - 13:00 Tallac Corkscrew bowl, skiers left entry Desolation Wilderness Area (including Emerald Bay) Avalanche Observation This is the crown profile, The crown from below, this shows about half the total crown I believe, This is the debris field, the arrow marks where the snowboarder had ended up in the tree and was buried up to his waist. His head and neck were above the snow the whole time, and had no injuries., This pit below the final ridge on the skin track, East facing, 33degrees 9000ft shows the weak layer which was very reactive CT3 for me and CT 13 for the one on the right. Not sure if this is a new layer or if this is an older, seems like a new layer and the new storm snow/wind slab.
