Avalanche Summary
Loose wet avalanches were reported up to size 2.0 from steep East aspects in the AM and from steep West aspects in the PM.
Snowpack Summary
The surface snow is likely undergoing a melt-freeze cycle on all but high elevation shady aspects. The record low snowpack is generally well settled and strong; however, facets with an associated laminated crust still lurk near the base. Recent snowpack tests on a SSW facing treeline slope gave hard but sudden results on a crust laminated with facets down 118cm. Below that, facets and depth hoar were found down to the ground. Although warm temperatures tend to promote settlement and strengthening over time, the initial strain could easily reawaken these deep persistent slabs.
