What you cannot see in that photo is the lateral blast of ash that obliterated forests 20 miles to the north of the volcano. Wind not required.

And once again, St. Helens was a midget compared to Yellowstone. A supervolcano like Yellowstone can radically alter the very climate of the Earth. Pushing out ash at right angles to the wind is chump change compared to that.

Good God man....I am not concerned with 20 miles...

The map depicting what occurred 70,000 years ago, in #2 shows ash fallout going west and south clear down to Houston Texas...Into Mexcio, and blowing west into California for Gods sake....LOL!

My simple question to you Mr. dirtboy, is for the past several hundred years, prevailing winds and jet streams blow west to east...

If this thing went off today, would the ash normally and likely head due east/southeast or would it travel west and due south into Mexico as shown in #2?

((wow))

"Pushing out ash at right angles to the wind is chump change compared to that."

Some fail to recognize that the massive release of thermal energy can send dust and ash flying laterally at near sonic velocities.
