Waggler,
Sounds like you might have a atory to tell?
My story isn't all that dramatic, but;
I was living 75 miles due north of St. Helens, I lived up on a hill, every couple of days I'd walk out (when it was clear) and look south at the mountain. Every once and awhile there would be an ash plume going up in the air a couple thousand feet above the summit.
St. Helens was a very symmetrical mountain, very similar looking to Mnt. Fuji. Over the preceding days I had been watching an area on the NE flank of the mountain known as the "dogs head" as it expanded outward like a big pimple. I remember remarking the evening before it blew that it sure looked like something was going to happen soon.
The morning (Sunday I believe) that I heard it erupted I walked out to take a look, it was a clear sunny morning with a slight haze. I was looking southward looking in the same area I had seen the ash plumes before, It took me a minute to realize what I was witnessing was enormously bigger than anything I had seen before, a plume rising over 65,000 feet into the sky.
I immediately jumped into an old car we had around the place and headed south on I-5, then went east on Hwy 12. This entire drive was to the west of the mountain out of the ash fall zone. It was an amazing sight the whole way, the freeway was lined with parked cars.
A few of us formed a little caravan and headed east on 12 until we got to a road block. We congregated there for a bit, then for some unexplained reason the game warden who was manning the road block took off. We all looked at each other, shrugged our shoulders and did what any sane person would do, we pressed on eastward getting ever closer to the solid looking gray wall of ash that lay to the east.
The gray wall was approaching, when I say wall, that is exactly what it appeared like. The truck in front of me disappeared into the wall, I followed closely behind him literally feeling my way along the shoulder, if I stuck close enough to the truck I could make out his tail lights, that helped a lot. We proceed along for a couple of miles until we encountered a State trooper manned road block, the block conveniently located next to a small country convenience store. There was a pretty lively party going on, one I will never forget. Spent a few hours there until venturing back home.
Most of the vehicles were becoming inoperable due to clogged air filters. Luckily my rig didn't have an air filter. I imagine all that abrasive dust sucking through the cylinders probably put what amounted to tens of thousands of miles on that rig in one day.
