Trend
Increasing Danger
Problem #1 Comments
Temps were high, and the snow surface was saturated on W-S-E aspects. There were many signs of natural wet-loose slides especially around rock bands and cliffs. I did not see any evidence of the water percolating down to old weak layers and producing wet slabs, but it may be possible with extended warm temps and strong solars.
Avalanche Problem #2
Problem
New Snow
Problem #2 Comments
Aside from yesterday's avalanches failing 10-18" down, I did not see any evidence of new avalanches on this layer. However in a pit dug at 9613' N (340°) I got a CT11 down 25cm. The failure was beneath a thin mf crust. Fine grain facets may be the culprit.
Comments
Avalanche Problem #3:
Persistent Weak Layer
I did not observe any activity on the NFL down 3-6'. However, a poor snow pack structure persists, and I would not trust it. In the pit that I dug, the facets that the majority of the avalanches have failed on this year (above a mf crust) appeared to have begun the rounding process, but the depth hoar (below mf crust) remain angular and 2-3mm in size.
