General Comments

We triggered several fresh wind slabs today in the Wellsville Range.  Most were small and isolated to the ridge and sub-ridge lines and would not run very far.  One was mid-slope on a two-week old bed surface in an obviously drifted pocket on the lee side of a small spur.  The 1' deep x 30' wide soft slab broke on a slope-cut and propagated in front and behind me....  It didn't run far (50')  before stopping in old debris chunks...
