Chilliwack River Valley

Arctic air receding through the day, warming to -5 in the alpine. Observed 30cms storm snow bonding well to a soft underlying crust on E aspects around 1600m. E Facing gully feature observed to have run full path during last cycle. Approx 1m crown, possibly more than 100m wide, running 750 vertical meters. Travel from valley bottom is arduous.

Presumably triggered naturally during last cycle, Feb 6-7th. 1600m E facing alpine slope.
