Appears that the pre-frontal rain/snow line reached maybe 8k on Wednesday; all aspects have some fall-out from that - either some friable crusts at low elevations or 2mm rain crust in the mid-elevations. This is now buried under a couple inches of small diameter graupel that fell during frontal passage. In the mid/upper elevation transition zone, the early week heat wave has taken its toll with thermal crusts on all aspects; again now buried by a couple inches of new...or otherwise scoured by the winds. One could see rollerballs on some northwest slopes at 8k. Low elevations have this superficial structure but damp below to the ground.
