Avalanche Summary
Avalanche reports have been limited due to very few information sources this time of year. If you have been out, please post your observations on the Mountain Information Network (MIN).
Snowpack Summary
Cornices are BIG and when they fail there is the potential to trigger very large avalanches on deeply buried weak layers. Below the surface there are numerous crusts in the upper 100 cm of the snowpack. A layer of sugary facets around a crust can be found near the bottom of the snowpack which has been dormant for some time. Large triggers, such as a falling cornice, or the major warm-up occurring this week could trigger this layer.
