More detailed information about the avalanche: 

The BAC team went to check out conditions at the 108 and the BWRA today. On the drive over we observed many large avalanches in the Mt. Emma range. Avalanches released during the Tues-Thursday storm. Very unusual cornices formed on both nothwest and northeast mid to high elevation slopes. Cornices formed on the upper third of leeward side slopes due to very strong winds.

We also observed an avalanche by Devils Gate in what we named "Devil's Depth Hoar Bowl" that may have run on buried weak layers but it is hard to know unless we travel up to the crown line.

Highway 108 is currently plowed to the MWTC but not yet to the People's Gate. The 108 up to the BWRA has very deep snow and is very difficult to travel on right now.
