From email on 12/18: "The avalanches looked to be about 36 hrs old, and were found on N/NE and SE aspects. About 5 avalanches were observed in total. Very minimal wind effect in regards to the avalanches, and the landscape in general. The avalanches were all about 30-40cms deep, and a couple were over 100' wide.... The weak layer was a layer of 2mm facets that formed beneath a m/f crust."
