Observation: Summit
Location: Fresno SE Ridge
This storm brought in warm temps overnight without a decent freeze. With the day before being warm the snowpack hasn’t had a good freeze in a while. It seems water is working its way down the snowpack dissolving MFcr layers observed in a pit dug the week before. This could make the facets at the bottom of the snowpack more active.
Obvious signs of instability
Observer Comments
On the skin track up, I experienced several areas of cracking and collapsing on South and East Aspects propagating around 6ft around me.
