Two large skier-triggered avalanches on Saturday provide fresh evidence that you can trigger dangerous avalanches. These most dangerous places are thin, rocky slopes with a thinner-than-normal snowpack. These two avalanches were on thin and rocky southerly slopes above treeline.
Don't count on obvious signs of instability such as shooting cracks and sounds of collapsing to warn you of an impending avalanche as these signs have mostly subsided. If you choose steeper terrain, after carefully evaluating the snow for a consistent and deeper depth, select slopes with clean runouts that don't end in terrain traps.
