Bulletin d’avalanche

You can trigger an avalanche in areas where you find about ten inches or more of new or drifted storm snow. You are most likely to trigger a dangerous avalanche on upper elevation slopes where wind-deposited snow has formed a more cohesive slab. Avoid terrain with evidence of wind-drifting such as fresh cornice growth, smooth, lens-shapes pillows or sculpted features, and watch out for unusual loading patterns from easterly winds. Retreat to more wind-sheltered areas or less-steep slopes if you experience cracking in the surface snow. Stick to lower-elevation areas or slopes less than about 30 degrees steepness for safer options.
