Terrain and Travel Advice
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
- Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
Problems
Wind Slabs
Thin pockets of wind slab are possible where wind has deposited sufficient snow into lee terrain features at upper elevations. Wind slabs may be especially reactive where they sit over a crust.
