Gallatin National Forest Avalanche Center

Crown profile of N-R4-D3-O broke on 2/18 or 2/19. Dug in shallower end of crown. Estimated up to 10 feet (3m) at its deepest, avg 6-8 feet deep crown. 700 feet wide.

This snowpit was part of the accident investigation of an avalanche that occurred on 2/14/2021. 1 splitboarder was killed.

The facets at 145-147cm broke when I pried the column from the pit wall after an ECTX. This layer is the weakest in the pit, but on this slope, not very weak.

Surface hoar layer at 164 cm does not seem to be a player anymore. After the ECTX I pried the block and it did not break on any of the "weaker" layers.
