You can trigger deep and widely-breaking avalanches from a distance and from below. You may not experience audible collapsing or visible cracking before triggering a slide.
South and southwest-facing slopes, and slopes less than about 30 degrees in steepness without steeper slopes overhead offer the safest riding options.
