Most wind slabs are a few days old and could be hiding under a dusting of soft snow. While they may be tough to spot, they should also be harder to trigger. Look for larger clues like well developed cornices or big drifts to point toward potentially loaded aspects. You may also feel the change in the snow under your feet. If you notice slightly firmer snow on lower angle terrain, wind slabs likely exist in nearby steeper areas.
As these potential avalanches become more difficult to trigger, it starts to take the “right” piece of terrain. You’re most likely to cause an avalanche in rocky complex terrain or on unsupported slopes. So, take a good look before you commit to a confined chute or travel above cliffs. In these type of area even a tiny slide can take you for a nasty ride.

Well developed cornice lines can help you anticipate potentially wind loaded aspects.
