Report from ESAC observer:

Skied in the Little Onion Valley yesterday (2/15). Not too much to report other than that the SW winds were stronger than we expected early on too. Obvious transport at ridge top level and some minor slabbing starting to happen in the canyon with the down slope winds. Previous Loose Wet slides on sunnies D1-D2 all over the place with origins up to probably 12000'. Melt freeze crusts on sunnies as well. Strong solar input yesterday, but little softening at upper elevations due to wind. Good "corn" skiing 9000' and below. Nice dappled pow skiing in sheltered tree areas above 9000'. Observed a couple D1 loose dry slides in very steep rocky terrain at highest elevations secondary to blowing snow. We approached the East Colouir of Black Mountain and found breakable MFCr on the apron. The snow started to dry out in the colouir itself, but still breakable and not appealing to skiing so we turned around. 

 

Evidence of previous D3+ in last storm in Little Onion Valley. Same coming out of Sardine Canyon D3.5. Newer D2-2.5 wet slides on top of old debris from Sardine Canyon and east aspects along mining road which leads from Onion Valley Road into Sardine Canyon.
