More detailed information about the snowpack: 

I went for a quick afternoon tour up to the Mammoth crest via Red Cone ridge to get a feel for the extent of fresh wind loading with today's strong winds. Leaving the car around noon skies were overcast, the temperature was around freezing, and sporadic moderate winds kept things feeling a bit brisk. I did not observe and flagging on ridge tops along with our ascent. Though once we poked above treeline, moderate winds with strong gusts encouraged a quick transition and some wisps of blowing snow were observed along exposed ridgelines. I did not observe any significant transport occurring. I found some small pockets of fresh wind slab up to 15 cm on small leeward depressions and the top of Red Cone bowl, but I did not observe any concerning slab development on my tour today.  Surface conditions were pleasant on our descent to lake Mary. With the exception of refrozen tracks and the sporadic area of breakable crust, surface conditions consisted of recycled powder in sheltered trees and wind textured soft snow in the more exposed areas east of the ascent ridge.  No cracking, collapsing, or recent avalanche activity was noted on our tour today.
