Great shot^!!!
The eruption destroyed an amazing amount of territory, it also created some new features-
Coldwater lake, 5 miles long and up to 180' deep. The eruption plugged up the former river's outlet and a new lake was born
When the eruption happened I was 150 miles away half asleep on a queen size water bed... I felt a thump through the waterbed and thought what in the world would make a 1500 lb waterbed jump?
Turned on the TV a bit later and found out, I could see the plume clearly from home.
