Red Flags Comments
Some cracking in the storm snow was observed when we would walk above an unsupported skin track or make a switchback. Hand pits took a moderate force to get storm snow to release from the n/o interface. In the area that we traveled it seemed like the storm snow bonded pretty well and the concern was in slight hardness changes within the top 30-45cm of the snowpack.
Avalanche Problem #1
Problem
Persistent Weak Layer
Problem #1 Comments
Not laying it to rest yet. There are still specific areas where we can find loose FC with a slab on top that produce avalanches. These avalanches have been occurring mostly at mid elevations on the polar aspects. Our pit today didn't raise any red flags in terms of strength but structure is always more important and that is a single data point in a big mountain range. Video link attached below.
Avalanche Problem #2

Trend
Decreasing Danger
Problem #2 Comments
See above. Storm slabs usually heal relatively quickly but can't be trusted when they are on top of a persistant weak layer, which, is what we are dealing with right now.
