More detailed information about the avalanche: 

we knew wind slabs were our primary concern but didn't 

know how sensitive they would still be. Stomping on

a small cornice, we were able to trigger a small wind slab

that took a bit of force to release. It slid on the super bowl 

crust, but did not propagate. Nevertheless, we choose a slightly 

less commiting line and had small manageable loose snow sluffs that did not 

run very far all running on the super bowl crust.
