Observations

1245, NE wind, gusts of approx 15-20mph, partly cloudy with scattered sun.
HS 170
P 170-150cm (wind slab)
P 150-130cm
1F 130-110cm
4F 110-75cm
F 75-25cm
1F 25-0cm

Surprised to find no super discernible rain crust. Still easily found multiple failures within top layers of snowpack.
CTE2 SP @ 150 and 130cm.

I’d personally avoid all avalanche terrain in Mission Ridge area. The snowpack is touchy and needs time to heal after the historic amounts precip followed by strong winds.
