Today we toured up towards point six. We found instabilities in the top 5 inches (12cm) of snow. This layer was easily sluffing off and could easily catch you off guard in steep terrain. We stuck to slopes free of previous wind loading and terrain traps.
Other observations:
• Areas with less than 40 inches (1 meter) of snowpack continue to weaken with cold temps. We identified defined .5mm facets around a foot down (35cm)
• Pockets of Surface hoar found. This could become a layer of concern if buried.
• We dug several pits in various locations and had no propagation in extended columns test
