Recent heavy snow and strong winds are creating dangerous avalanche conditions. You can trigger an avalanche where you find a cohesive slab that rests over deeply buried weak layers. Wind-drifted slopes above treeline are the most dangerous and if you trigger a slide here, it can become very large, very destructive, and impossible to escape. Shooting cracks and collapsing are clear signs to move to lower-angle terrain, but these may not be present before a slide breaks. You can also trigger an avalanche on wind-sheltered slopes, these will be relatively smaller but still enough to bury you. Your best course of action is to stick slopes less than about 30 degrees with no steep terrain overhead.
