"Downwind"
Heck, no sweat, I’m safe. At least until the earthquakes flatten everything and the ash cloud encircles the earth, killing off food growth and dooming us all to starvation in the dark. Note to self: buy some ramen noodles and flashlight batteries.
The first angel sounded, and there followed hail and fire mingled with blood, and they were cast upon the earth: and the third part of trees was burnt up, and all green grass was burnt up.
Most prevailing winds do not travel west/southwest from Northwest Wyoming. They generally head due east, and southeast. If you had to be in the U.S. during a major event from that region, the west coast would probably be the safest place in regards to ash fall.
I’ll admit it....I’m dumb.
WHAT does “Age=1.3MYa”, etc., stand for?
