Snow Characteristics Comments

There was just a skiff of new snow from last night, the light density powder from Sunday has settled out and become boot deep, medium density creamy powder, in wind exposed terrain there were wind crust of varying thicknesses from a thin wind skin to breakable crust to hard-slabs in some cases. Low angle S facing was still hanging in there at the end of the day.

Went to take a look at the PC Ridgeline before the next storm arrives to get a handle on what is going on. Travel was up Willow Heights, West Monitor, South Monitor, No Name with a exit out of USA Bowl. There didn't appear to be much avalanche activity during the last storm but if there was the wind from yesterday and the night before would've erased the evidence. West Monitor, South Monitor and Scott's Peak all had large natural cornice drops in them that almost made it to the flats but these cornice drops did not seem to produce any real avalanche activity, the one in West Monitor may have produced a shallow soft slab but not much more. Wind Damage was noted in both Monitors but down lower out of the wind in No Name the damage was negligible. My thought is the the PC Ridgeline got quite a bit less snow from the last storm thus less activity. The density inversion is starting to settle out but can still be identified while breaking trail but not while skiing. We've finally got som large cornices forming on the W Monitor ridge line and with it being fairly warm the last two days I was giving them a wide birth.
