Aspen

Wind-drifted slabs of snow rest over weak collapsible layers buried one to three feet from the surface. You can trigger an avalanche that breaks on this weak layer, propagates widely, and is large enough to bury you. You may not see or hear any obvious signs of instability, such as shooting cracks and collapsing, to warn you of dangerous conditions. As you travel higher in elevation these dangerous avalanche conditions are more widespread across different aspects.

You can find safer avalanche conditions in wind-sheltered terrain at lower elevations where the snowpack has seen a lot of recent warming.
