You can trigger a dangerous avalanche where the wind is drifting snow on to northwest through north to southeast-facing slopes. You can find drifted snow on steep slopes below ridgelines, cross-loaded gullies, and convex rolls. Avalanches can break wider than you expect and can step down into old snow resulting in an even larger avalanche. Shooting cracks and collapsing sounds are signs that you should move to terrain less than about 30 degrees.
