Re: Greg . . . wheres the smoke?
I am not following. . . I see two streaks in opposite directions. I have little doubt that these are debris avalanches especially after stumbling across that one on Mount Adams. While the one on Mt. A. apeared shorter and squater, when I looked at debris avalanches of Mt. St. Helens and then looked at the maps of them, they apeared very long and not very squat. . . I'm sure an arial photo of mount adams debris avalanche would demonstrate further similarities.
