Excellent riding out there today and the snow stayed dry on the northern half of the compass at high elevations.  The southwest winds moved a lot of snow and would fill in tracks on the ridges within 20 minutes. We stayed away from steep slopes that were heavily wind loaded but did get some activity off the ridge lines within the new snow (may have been slightly wind loaded). 

The first 5 pictures give a pretty good indication of the type of slabs we found. Although we were in the middle of the slabs when the slide started, the slopes were short and with enough speed you could quickly get off the slab.

The south facing slopes began warming up by late morning and were sluffing off pretty good piles as seen in the 6th picture.  We saw several shallow but wide slab avalanches initiated by snowmobilers in the Christmas Tree Bowl area.  There were several other wide slab avalanches triggered by skiers in the Tony Grove area.
