My Zimmer Area

Date

Went for a tour today in the Green Lake/Mt Zimmer area. We found around 20cm new snow that was mostly well bonded to the old snow surface. Snow depths are generally over 120cm, but as expected there are thin areas. We dug a pit in one of those thin spots at 10,000 ft on an E aspect, with HS around 110cm. We found the new snow to be sitting on a layer of larger (1-1.5mm) NSFs, and got an ECTN 20. The remainder of the snowpack to the ground consisted of faceted crystals 1F-4F in density. Stability is good for the moment across the area we observed, although the new snow sluffed easily on 40 degree slopes on a SW aspect later in the day after significant warming. We did not observe any collapses, cracking, or signs of slab avalanche activity (1x Natural D1 Dry Loose observed in steep S facing terrain 11,000 ft, 1 ASc D1 in similar terrain).
