You can trigger an avalanche where thick slabs of snow rest on top of weak layers near the ground. The most dangerous slopes face northerly and easterly. You can trigger one of these avalanches from a distance or the bottom of a slope. Give suspect slopes a wide berth and maintain extra space between your route and potential runout zones. Shooting cracks and collapsing are signs of instability, but they may not be present before you trigger a large avalanche. Look for safer riding on slopes that are less than 30 degrees without steep slopes above.
