Avalanche Summary
In the past few days only one avalanche was reported in the Adder area. It was a small (size 1) remote triggered avalanche on a north aspect in the treeline. The reported also described a few older avalanches up to size 2. See the whole report here.
If you are getting out in the backcountry, consider making a post on the MIN (Mountain Information Network). You can share riding conditions, avalanche or snowpack observations, or even just a photo or two.
Snowpack Summary
10 to 20 cm of new snow is falling on wind-affected snow on all aspects in wind-exposed terrain, in sheltered terrain near-surface faceting and in places surface hoar have been reported. On sunny slopes this new snow will fall on a hard sun crust.
A widespread crust, combined with a thin layer of weak facets in some areas, can be found 30 to 70 cm deep, under generally low density snow. Otherwise, the mid and lower snowpack contains no other layers of concern.
