You can trigger an avalanche where you find drifts of firm snow. On northerly and east-facing slopes, these may break above you in steeper connected terrain. You will likely find unstable snow below corniced ridgelines and along gully walls. If you feel firm, hollow snow that cracks or collapses, you should head to lower-angled or wind-sheltered/scoured slopes.
