  South and westerly winds from recent storms were strong enough to form windslabs at treeline and above on Monday.  They can be found near ridgelines in leeward terrain primarily on north and easterly aspects. Cracking snow and hollow or drum like sounds under your feet are good indicators you've found them.  Funneling of wind through saddles and around outcroppings has transported enough snow down slope to form windslabs in leeward terrain at middle elevations.   While likely to be small, potential for injury still exists if you are carried over cliffs or into trees.

  While the likeihood of triggering a persistent slab avalanche is trending down the consequence of doing so remains high.  This problem is most likely to be found in the northern reaches of the Purcell range where where colder temps and a shallower snowpack has allowed these weak layers to persist.  In the East and West Cabinets this problem is less likely to present itself as the snow is deeper and weak layers are bridged by a thick rain crust formed in late Decemer.  Take time to dig into the snow to identify these layers before committing to consequential terrain.
