Travel and Terrain Advice
Heightened avalanche conditions on specific terrain features. Be on the lookout for isolated steep slopes and storm slabs that have formed where the terrain is convex or otherwise difficult to support snowpack. The snow is well-cooled, and even with gentle slopes, it is a good day for powder skiing with good underlying support. There are "terrain traps" scattered throughout the forest, including holes in creek bottoms. Use your imagination to see what is hidden under the snowpack and choose safe routes. The mountain is expected to be crowded. Keep in mind the principle of stopping at safe places and moving at intervals. And pay attention to the movements of other groups in the same terrain. Have a good day.
