Comments
Went for a tour in Lambs today to look at how the new snow was bonding to itself and the old snow surface, as well as investigating weak old snow surfaces. Cracking was observed when walking off the skin track (see photo below). Within the new snow there were some noticeable density changes, mainly a 10cm layer of slightly denser new snow sitting at the surface. With the limited visibility I had, no recent avalanches were observed. Stability tests showed cracking within the new snow and at the new/old snow interface with ease, no propagation in an ECT due to lack of a slab. Where I traveled today the new snow was soft, however, this will change with the coming wind and settlement. I imagine soft slabs and loose snow avalanches could show themselves on steeper slopes today.
I dug on two slopes: N facing 7250' (out of old wind zone), and NW facing 7840' (in old wind zone along ridgeline). In both locations, facets can be found beneath the new snow. In zones hidden from the old wind, new snow is sitting directly atop this weak snow. In the old wind zone, I found an 8" 4F slab separating the new snow from the underlying facets (see photo below). I'm interested to see when we start seeing avalanches on these newer facets once the slab develops. Based on how variable the old snow is, I imagine the dragon will first show itself in pockets.
