Terrain and Travel Advice

  • Watch for changing conditions today, storm slabs may become increasingly reactive.
  • As the storm slab problem gets trickier, the easy solution is to choose more conservative terrain.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
