More detailed information about the snowpack: 

After seeing evidence of a localized wet Stormslab across Leavitt Creek & the variable precipitation forms I dug a pit on the opposite (Leavitt roadside) of the creek. I'm certain I was on an amazingly deep wind deposit, but it is commonplace out there these days. I was in view of the slide-path that gave us the historic Avalanches earlier in the season, fully avoiding any under-cutting of that slope. On an eastern 15degree aspect +390cm existed & air temp of 1 degree Celsius with strong easterly winds. The most recent 20cm saturated snow is the primar concern as it sits upon a less dense 20cm colder powder with a sun crust acting as the bed surface interface 40cm below the surface. Below the sun crust is yesterday's surprise 15cm of new lighter density snow which is right side-up. Two separate ECTs gave failure results at tap 14 at the buried 40cm crust, with Q3 irregular propagation ECTP14. MY results didn't inspire confidence nor did the visibility & increasing winds so I left the area. Rains had effected this area above 8000' and ice was breaking limbs & blowing off trees.
