Persistent weak layers of weak, sugary, faceted snow are present on all northerly-facing aspects at all elevations. Slabs 2'-3' deep exist on top of these weak layers near and above treeline. Additionally, cold temperatures and a lack of snowfall for most of January has formed weak layers around the compass and elevation zones. While recent warm temperatures and time have helped the snowpack gain some strength, dangerous slabs are still lurking and can be triggered from far away. You may be surprised by avalanches breaking wider and deeper than you would expect. Give steep terrain a wide margin and stick to slopes less than 30 degrees.
