Travel and Terrain Advice
At higher elevations where bonding is difficult to progress, act with caution in bonding wind slabs on extremely steep slopes just below ridgelines and branch ridges. Watch for the presence of "terrain traps" such as gullies, cliffs, and standing trees below you that could increase the damage in the event of an avalanche.
