More detailed information about the avalanche: 

Toured into the cabinets and observed several large debris piles from avalanches that must have happened during the atmospheric river last week. The largest ones were at lower elevation, but it looked like about 75 percent of slide paths we passed had gone naturally. The snowpack was frozen solid when we went through.
