General Observations

Gully 1, up to 4000', N aspect, mostly cloudy, 8° F, NE wind, light to moderate.

Found surface hoar 2-4 mm in the flats and alders.  No surface hoar was found above bush line or in the gully. 

 At 3700', N aspect, 25° slope, found a snow depth of 200 cms.  Stability results yielded an ECTN22 down 30 cms, breaking just below the 12/9 rain crust with a Q2 shear.  The 12/9 rain crust averaged 7 cms thick at this location.
