Was anyone around last time Mt St Helens went up ?
Yup. Went right over the top of it the day after the 1980 eruption. All I can tell you is that at 370 we didn't seem to have any problem at all and I got some great photos.
Although it was pretty nasty down low...
I was telling someone about this yesterday, and she said, "I remember the eruption. I lived in Salem, Oregon at the time and we could see it. I was 11 years old and in fifth grade.
I'm old.
