Travel and Terrain Advice
This is a very dangerous avalanche condition. Even if you are in the woods, consider whether there are any large start zones above you. Also, remember to be on the lookout for hard, frozen slopes under the fresh snow. For less experienced groups, this is the day to enjoy the fresh snow in the ski area. If you do so, do not enter the closed areas. This is for your safety and at the same time it is important for the safety of other guests.
