Northerly and easterly aspects have buried weak layers where you could trigger a deadly avalanche. The most dangerous slopes are shallow slopes or those with rounded-smooth pillows where the wind has drifted snow. You are unlikely to get any snowpack feedback, such as cracking or collapsing, and multiple people could ride a slope before you trigger an avalanche. If you trigger an avalanche at the surface it could step down to deeper layers. It is almost impossible to see trigger points under the snow so consider sticking to slopes less than about 30 degrees for safer travel or heading to aspects without a buried weak layer.
