Snow Characteristics Comments
Surface weakening, with a layer of near-surface facets in the top 3-5 cms. Still not especially weak, but something to monitor with loading likely by mid-week. HS generally < 1 meter where we were traveling (northerly aspects up to 9200')

Poor Snowpack Structure
Red Flags Comments
Rather weak snowpack with widespread facets throughout thinner snowpack areas. Sandboxing in some areas. Sunday/Monday storm snow providing a 4F- slab on top of F hard faceted layers.
Comments
Two tours this weekend involved looking at thinner snowpack areas in Big Cottonwood drainages (Mineral/Cardiff/Broads) where the snowpack is < 1 meter. Currently the snowpack is stable with a generally Low hazard, but also quite weak in thinner snowpack areas and it may become reactive with a series of moist & windy systems forecasted beginning mid-week. Several quickpits yesterday and today, and most everything is ECTX, or ECTN failing within recent storm snow or at the interface with the faceted layer from 1/1-1/4.
In areas where the snowpack is thicker (> 120 cms) the overall structure looks good, and buried faceted layers are continuing to gain strength.
Wind drifts are currently unreactive where we were traveling, but I would still avoid steep, upper elevation terrain facing northwest through northeast that has been windloaded as drifts are likely sitting on top of weaker facets.
