Comments
Looked at snow today at the upper elevations and lower elevations:
Upper Elevations: On Wednesday I was finding the interface at the interface between the storm snow and the old snow to be reactive, with cracking and easy shears. Today, I had dug several pits between 9,000' and 10,500' and everything showed instabilities to have settled out. This is no surprise given how warm and dense the storm snow is. I was also finding recent wind drifts to be unreactive to ski cuts.
Low Elevations: Rain/snow lines touched as high as 7,500 or even 8,000 and the top 10-20 cms of snow at the low elevations is saturated. I ventured into the lower reaches of Butler Fork and was finding dry snow ~20 cms down from the surface and this dry snow could be a reactive weak layer if temperatures warm at the lower elevations on Friday. My thinking Thursday night is to list Wet Snow as an avalanche problem for lower elevations on Friday.
Photos are of pits at (1) upper elevation, and (2) lower elevations.


Discussion of my thinking of current snowpack structure at the mid and upper elevations. (Excuse the vertical alignment)
