Terrain and Travel Advice

  • Be especially cautious as you transition into wind affected terrain.
  • Be alert to conditions that change with aspect and elevation.
  • Minimize your exposure time below cornices.
  • As surface loses cohesion due to melting, loose wet avalanches become common in steeper terrain.
