You could trigger a large avalanche in weak snow close to the ground on northerly and easterly aspects. You may not see widespread natural avalanches, but you can easily trigger an avalanche from below or from a distance, and the size might surprise you. The snowpack has been cracking and collapsing all week, but don’t assume the absence of these red flags is a sign of stability. Be careful in areas where you find more than about six inches of new or wind-drifted snow on other aspects. You could trigger a small wind-loaded pocket. On aspects with a buried weak layer, you can find safer riding on slopes less than about 30 degrees unconnected to steeper terrain.
