General Observations

2/13- Browns Creek up to 3800’/ SW-W aspects/ Clear/ Calm/ 22° F @3800′

Collapsing- No

Shooting Cracks- No

Avalanches- No

The first couple of hundred feet out of the valley found 2mm developed facets under a rain crust in steep terrain that was 40 cms down.  Above that elevation found 30-40 cms of uncohesive snow on a hard bed surface that was created by the 2/1 wind event.  New snow had bonded well to the crust and showed no signs of instability within the surface snow.  In a pit at 2000′ on a west aspect found a 20 cm layer of  1 finger, wind  affected snow down 40cms.  Below this,  4 finger snow existed consisting of rounding facets that showed hard results (24-30+) in  ECT‘s with propagation.   Faceted snow below hard wind slabs may become an issue in the future when large loads are applied such as rapidly changing weather or cornice fall.
