Avalanche Summary
Recent avalanche activity in the region has been limited to small loose snow avalanches running in steep terrain. This has been more prominent on sunny slopes as the radiation penetrates the snow surface. Glide cracks continue to open.
Snowpack Summary
Minor surface hoar growth continues in areas that are sheltered from the wind. Surface facetting is loosening the upper layers, allowing for a slight increase in sluffing. Recent small surface hoar is buried beneath a thin layer of cold dry snow. Wind slabs continue to develop due to the availability of loose snow for transport. Deeper weak layers have not been reactive.
