You might trigger an avalanche that breaks two to four feet deep on slopes steeper than about 30 degrees. The buried weak layers are becoming less reactive as the snowpack is adjusting to last week's storm snow. Cracking and collapsing may not occur before a slide breaks deeply so do not get lulled into a false sense of security. Avoid areas on a slope where the snowpack is thinner; these are the most likely trigger points. Consider your terrain choices carefully, if you were to trigger a slide on a larger slope it could grow in size quickly and have dire consequences. Sticking to terrain less than about 30 degrees will help keep you safer.
