It's a bit difficult to describe the size of this avalanche, classification of HS-AM?-d3-r5-O doesn't quite capture it. Again, hard to know for sure, but it looks like most of the cirque avalanched in one big event…..

A person feels pretty small in this country.....This is looking southeast from Cornice Ridge at my partner Josh dropping into the bed surface on the southern part of the avalanche

I'm glad nobody got caught in this monster... Debris piled deeply on trees and into an abrupt sink-hole below the slope...
