Gallatin National Forest Avalanche Center

Poor structure, but improving stability. CPST 25/100 end

Added (doubled) slab on one PST column and it collapsed/propagated under the additional weight as it was added (0/100 end @ 80cm, SH layer).

All collapses were in the trees on a very shallow snowpack.

Snowpack was much deeper with better structure than a pit we dug later in the day on a S-facing slope on Scotch Bonnet
