Gallatin National Forest Avalanche Center

Very cold and windy

Experience huge rumbling collapse on this slope before digging pit.

Crown profile for a remote-triggered avalanche from about 50 feet away. SS-AFr-R2D2-O, 100' wide, 1-2' deep, ran 300 vertical feet. An avalanche of similar size released in an adjacent path with the same collapse.

HS was much deeper in this pit than it was in most of Teepee Basin. Able to get propagation with the ECT at 46 cm with three additional stout blows after 30 taps.
