Warm today and the winds backed off.  Temps at 9000' hit 47 degrees and just got to 32 degrees at 12,400'.  Winds remained in the low teens during the day.  Seemed like a good day to go for a long walk and get back into the South Fork Drainage.  Lots of variety out there right now from Wind slabs to Persistent slabs.  Was able to dig a bunch of pits and everything was showing something a little different.  Breakabale wind crust, to bullet proof hard slabs, and near surface faceting and softer winds slabs were found on the walk.  South aspects above treeline were corning up around 11 AM.  Found a large 4' old crown that ran on the ground some point during the last storm?  (See Video).  Tracks from Lake Fork on Tuesday were covered by recent wind loading.  Loose wet avalanches were observed on drive down the canyon below 9000' on North Aspects.  Was able to assess shallower snowpacks today.  The buried wind slab before the last storm seems to be healing but in shallow areas we are still dealing with basal facets.
