Gallatin National Forest Avalanche Center

Prior pit to this lower on slope, at top of steeper meadow had ECTNs at storm interfaces, no propagation, or obvious SH layers. Weak layer was not obvious until CT, and then ECTP 13 was a bit of a surprise. Shorter PST cut (15/100) was result of placing slab from previous test on top of the second PST, essentially doubling the load.

We dug in the crown of a recent avalanche. The slide appeared to be triggered by a falling tree. This was likely the result of very strong winds that were impacting the area.

CPST 32/100 end at 76 cm's

CPST 26/100 end

Avalanche warning and near historic snowfall. 6" of SWE in last 6 days.

It was raining 500 feet below our pit location. Stability decreased as you dropped in elevation.

SH has gotten stronger quickly.

Well developed depth hoar near the ground wasn't reactive. However, with a big load 1-2" of SWE, avalanches are still possible on this layer.
