Poor Snowpack Structure
Comments
Took a walk out to Maybrid Gulch to see what the snowpack looked like. Temperatures were in the teens and lower 20s with very mild wind. The Sky was overcast for most of the morning but started to get patches of blue sky on my exit at 1:00PM.
I did not get any cracking or collapsing on any test slopes that I walked on. The snow pack ranges from 100cm to 150cm in the places I checked, but looks much thinner in the upper elevations where winds and avalanches have done their damage. The south east corner of the headwall had a large crown that spanned from the east facing side all the way through the middle of the north facing wall. The crown was still somewhat defined so I imagine that it went late in the last wave of snow last weekend. The upper 2 cm of snow is starting to facet and will likely be a weak layer that we will have to watch for once it is buried.
Snowpit 1 (West Facing - 9,800ft - 35 degree slope)
Snow was about 100cm deep with a very good structure. Top 20cm was settled powder that got gradually more dense all the way to the ground. I did not find any faceted snow below any of the layers. ECT produced no results.
Snowpit 2 (NE Facing - 9,800 ft - 26 degree slope)
Snow was 150cm deep in both of the NE facing pits that I dug. As you might have guessed, the structure is garbage. Bottom 30-40cm is completely faceted and has no structure. Infamous October crust exists with a thin layer of facets on top. What was interesting about my NE facing pits was that I did not get any of the extended columns to fail. What this tells me is that the snowpack is adjusting to the new load, but remains very complex. I would imagine the areas with thinner snow are have higher levels of danger. In my opinion it is still to early to lay the cards on the table for aspects on the N end of the compass.
Danger on the north end of the compass remains at considerable/scary moderate. Danger on other aspects is moderate.
