Terrain and Travel Advice

  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Carefully evaluate steep lines for wind slabs.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
