Here's a little more information on the small avalanche Ted & I found in Superbowl. The surface hoar is still in play in some areas.
Ted walks us through a shovel shear and compression test near the crown.
After the initial failure at the ground in our ECT, we noted a second failure plain in the mid-pack. Upon further investigation, we discovered a folded over buried surface hoar layer was the weakness associated with this avalanche.
