Around a foot of new snow and strong winds created dangerous avalanche conditions. The most dangerous areas are wind-loaded slopes near and above the treeline on the lee sides of a ridgeline primarily facing easterly directions. Identify and avoid steep wind-loaded slopes with a wave-like surface appearance, a hard hollow feel to them, or where you actively see snow being blown onto the slope.
You might be able to trigger a larger avalanche on an unusually weak layer buried about two to four feet below the snow surface on most slopes facing west through north to southeast. You might be able to travel on a slope dozens of times before you find the shallow spot, impact the weak layer, and trigger an unsurvivable avalanche. If you choose to travel on steep slopes on these aspects of concern avoid shallow, uneven, rocky slopes and stick to slopes with no terrain traps such as a cliff, creek, or dense trees below you.
