[No photos or video as my phone battery once again died in the cooler temperatures ..... pretty soon I'll be using a teletype machine.]
Take home from today:
- Most hazardous day of the season so far. Touchy conditions with lots of red flags.
- Weakest snow was either (1) a density inversion within the storm snow, (2) the interface with the Wednesday storm snow (a thin layer of facets formed overnight Thursday into Friday), or (3) within the lower-density snow that fell on Wednesday.
These were the weakest layers today; as (1) and (3) gain strength, the persistent weaknesses deeper in the snowpack may become reactive.
- A few pits outside of wind-affected terrain showed 20-25 cms (8-10") of a denser storm snow slab. Full propagation extended column tests (ECTP 8 Q1) failing at the interface of - or within - the Wednesday night storm snow.
Less concerned about storm slab problem, and more about persistent slab.
Solid Considerable today, with an even higher spike in activity and conditions in the early afternoon.
