More detailed information about the avalanche: 

Upon approaching the BWRA on 395 we noticed to the Southwest of the rec area a very large R4D3 avalanche near Mt Emma. Throughout the day we noticed many avalanches of different sizes & variety on all aspects at, above, & below treeline. The remnants of mid-storm avalanches was apparent. Loose Dry, Storm Slab, Wind Slab, Cornice Fall, & later in the day Loose Wet slides had released. An average depth of new snow was 100cm, just shy of 4 feet! The cold dry snow is ready to move on slopes steeper than 30 degrees, especially with afternoon warm-up.

We had a raging blizzard that started on Thursday & finished up Saturday dumping around 100cm (4') of very light density snow. It was a cold storm with winds swirling but dominated from the SW. Getting yourself into trouble is easily done out there dont tempt it...
