Recent loading by new snow, wind, or rain
Temperatures topping out near freezing, quickly clearing skies and 4" of new snow brought a nice day and a good refresh to the BWRA. New snow fell on a mosaic of variable crust layers in the upper snowpack. A shiny firnspiegel crust was intermittant and most evident at higher elevations. Below was a unreliably supportable wind crust covered by either new snow or firnspiegel. Strong winds overnight continued during the day today, moving snow over ridges and exposed terrain while leaving scoured zones behind.
New wind slabs exist in near and above treeline terrain. We observed a small slab release below a cornice. Test slopes resulted in minor cracking without release.
