The few slopes where you can trigger a dangerous slab avalanche are on wind-drifted slopes at upper elevations, generally facing northwest through north to southeast. Don't expect to see any signs of instability, such as cracking or collapsing, before you trigger an avalanche. You might be able to trigger them from the bottom of a slope or from a distance, so be aware of steep slopes above you and other parties nearby. The easiest way to reduce your chances of being caught in an avalanche is to stick to slopes less than about 30 degrees when you are traveling on these aspects of concern. Low-elevation, wind-sheltered slopes also offer safer travel options.
