Dangerous avalanche conditions exist. The most dangerous slopes face north, northeast, and east, but you can trigger an avalanche on most slopes near and above the treeline that held snow before last weekend's storm. Now that the weak snow is buried around two to four feet deep you may not see typical signs of instability such as cracking and collapsing in the snow before triggering a large and deadly avalanche. You can also trigger one of these avalanches from below a slope or from a distance so avoid traveling both on and underneath steep slopes facing west through north to southeast. Safer travel options exist by sticking to south and southwest-facing slopes where the early season snow melted, or by avoiding travel on or underneath slopes steeper than about 30 degrees.
