Travel and Terrain Advice
The strong snowfall is over and the weather is slowly improving, but it is still a day to be vigilant for avalanches. Please choose your terrain carefully, watching carefully to see if the surface layer of snow cover has the characteristics of a slab. Large slopes open to the south have the potential to generate large avalanches. Continue to stop in safe areas, ski one at a time, check for "terrain traps" below, and look for "direct evidence" with good communication with your companions. If you choose the right terrain, this is a great day for great fresh snow. Have a great day.
