None. The clear skies overnight seemed freeze things up well. We didn't see any signs of instability even during our last run at 4pm.
Observation: Hatcher Pass

Snowpack
Non-solar aspects were smooth nice powder over facets about 40cm down. Upside down and punchy in places. The facet layer never whoomphed, but it was creepy enough that we didn't ski powder over 30 degrees. We skied one solar aspect and found great skiing on sun-softened sastrugi. We skied a long steep shady aspect that had avalanched probably on Sunday, but then filled in some and faceted some from clear skies. The cornice at the top broke off on a 5mm surface hoar layer. Then we lapped the low angle happy hippy powder near the parking lot Mike Wiegele Heli Ski style.
