Cool morning, but warmed up with a little bit of greenhousing noticed towards the mid afternoon. Clouds lowered at one point in the afternoon, and picked up a few flakes of snow, but then dissipated and the peaks were out again across the valley.

Lower elevations still have plenty of snow on these shaded aspects, and evidence of the Feb 28 avalanche cycle is aplenty. Many gullies and avalanche paths in this vicinity ran around that timeframe. The snowpack is now mostly supportable and well-transitioned to melt forms below about 4,400ft.
Above 4,400ft I found newer snow, though moist up to about 5,000ft. As low as 4,800ft I found evidence of the 3/8 faceted layer, but the layer was spotty to find and moist. Skinning from 4,400ft to 5,500ft was sometimes tricky with old debris, and the slippery crust not too far beneath the surface (15-25cm avg).
At 5,500ft on a NNW aspect I found a more consistent faceted layer and dry grains above the early March crust. Here I dug a profile in an obvious wind pillow. HS 214cm.
The 3/8 facets were down 30cm, only 1cm thick, 1mm and rounding but dry. Test results were:
Tilt Test moderate, planar
ECTN H down 30cm
PST 35/100 (End) down 30cm
PST 50/100 (End) down 30cm
Another profile on a N aspect at 5,800ft showed HS of 243cm
3/8 facets were down 27cm, 2cm thick, 1-1.5mm, rounding/dry and weak (F+). Test results were:
CTM SP x2
PST 25/100 (End)
PST 35/100 (End)
I was able to get localized cracking on skin track tests from time to time. I didn't get any whumphing, but had I continued up into areas where the snow was deeper/thicker wind drifts I would've expected it. The snow surfaces became slightly moist even on N aspects at 5,800ft by 3pm, with some rollerballs releasing on my way back down at 5,000ft or so.
