Snowpack Observations

Quick driving tour to check on conditions. Boot pen was nearly knee deep in weak, mushy snow off the side of the road at pass level.
Quite a few wet loose slides in the D1-2 range off most terrain, many of them were older but some D1-1.5's looked recent.
Of note were a number of glide cracks opening up in usual places, but also some unusual ones.
