Observed dozens of natural sluffs on all aspects, mostly at mid and upper elevation, on slopes above 40 deg. Sluffs ranged from D1 to D2 and ran on sun crusts on southerly aspects and old wind slabs on leeward aspects.
Observed one human triggered soft slab below Marmot Ridge, W aspect 4500' (SS-AS-D1.5-O) likely from 3/4 or 3/5.

Significant warming on southerly aspects , especially slopes with high angle of incidence. New surface snow warmed up througout the day enough to make a snowball. Observed one natural sluff on Microdot south aspect at 2pm. One natural sluff in Nosehairs south aspect 2-3pm.
No other signs of instability today.
Sunny and beautiful. 6" new snow from 3/6. Calm wind. 14 deg at 4505' at 2pm. 18deg at 3505' at 2pm. Warm enough for gals to skin in sports bras.
6" or more of new low density snow over fragile sun crusts, last week's faceted snow, and old wind crusts.
New snow glopping up, sticking to skins, and forming snowballs by 2pm on southerly aspects.
HS 155cm at 4000' S aspect
Valentines Day slab and persistent weak layer getting buried deeper and deeper. Found at 35 cm in this pit.
Multiple sun/melt-freeze crusts mixed with faceted snow, on top of buried deteriorating old melt freeze crust near the ground.
10 cm (4") Warming surface snow failing easily over new snow.
