The most concerning avalanches are those breaking on weak layers now buried relatively deep. These are becoming harder to trigger and less likely to happen, but it could be very big if you get one to go. You can reduce the potential to trigger these by avoiding slopes with shallow or uneven snow cover. Rocky convex rollovers, slopes that avalanched earlier this season, or typically wind-scoured slopes are all places where you can impact the buried weak layers. More recent snow and winds have layered shallow drifts on top. You can trigger avalanches in the recent snow on higher-elevation slopes. Avoid steep slopes where the snow surface is pillowed or wavy, often below cornices.
