Quick report

Throughout the day we had consistent whoomphing and cracking with shooting cracks on all aspects and elevations throughout the resort. The majority of these were not reactive beyond the initial settling. It looked like the backside of Fred's mountain cornice line failed in many places but visibility made it hard to see. In the morning the majority of our avalanche mitigation work produced minimal results with the one exception on sitting bull ridge, but in only one isolated place. As we set the mountain up, multiple avalanches were remotely triggered along our northern boundary as described above. Midway through the day as we continued our mitigation work into smaller more confined zones, like gullies, we triggered larger slides in the waterfall and screaming cheetah, also described above. Towards the end of the day it was observed that the majority of the north face of peaked went naturally. A photo will be included later.

A remotely triggered slide from the flats about 100' away. The lower section was triggered and then upper was also remotely triggered several hours later.
