Large and impressive avalanche that propagated across several terrain features from NE facing Talking Mountain Cirque, over a sub ridge into N facing Lone Pine, and over into the moraines of lower Middle Cirque. Occurred as part of a widespread natural cycle. Three day storm totals were up to 18" of snow and 2" SWE. Strong SW winds tipped the scale. Failed on early December facets.
