Comments
Today's focus was on (1) recent wet avalanche activity and (2) facet/crust combos on E and SE aspects.
1. I saw generally minor wet avalanche activity, but when leaving the canyon at 3 pm, a sizable wet debris pile filled the apron on Superior, taking out recent tracks. I'm unsure when this avalanche ran, but it's an indication that wet slides can entrain a lot of snow on large slopes. It also appeared some of this avalanche involved a wet slab, likely triggered from a sluff of wet snow from above.
2. Digging on east and southeast aspects and sun crusts that formed earlier this month are evident in pits, but I was unable to get clean shears, indicating the crusts and adjacent slabs have bonded.
