Problems

Loose Wet

An icon showing Loose Wet

An icon showing Cornices

The diurnal cycle weakening cornices daily. A cornice drop can be hazardous on its own, or also has the potential to trigger larger avalanches.

  • Give cornices a wide berth when travelling on or below ridges.
  • Cornices become weak with daytime heating.

Aspects: North, North East, East, South East, North West.

Elevations: Alpine, Treeline.
