Terrain and Travel Advice
- The snowpack is generally stable; it may be appropriate to step out into more complex terrain.
- Make observations and continually assess conditions as you travel.
- Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
- Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
