Had a great view of the big one when it happened, we had seen multiple smaller eruptions prior but this was immense. We got plenty of ash from the prior eruptions but the wind blew the other way on May 8th.
My dad had worked a roadblock on the mountain the night before but got done around midnight. They had a 5 mile exclusion zone, which turned out to be plenty of room on one side, and not at all enough on the side that blew out. Most of the people killed were outside the exclusion zone.
I later watched on TV all day as houses and bridges were knocked down by the mudflow, then happened to be on a school bus crossing a bridge when the mudflow debris made it to us the next day, but by then it was just a mass of logs and debris in the Columbia and not capable of knocking down anything. It clogged the Columbia though, and it stayed a problem for a long time.
I watched houses, docks, tens of thousands of logs, and other debris wash out the Columbia river. Every wing dam (log jetty) had hundreds of logs jammed up against it all summer. Know where a house is that was floating by, it was salvaged, towed in, and put up on skids and is currently in use.
There were huge pumice rocks that came down the river as well. All the logs came from a logging camp, some houses were built from lumber cut from them, as a home sawmill turned into a money maker. The logs supplied firewood for at least 10 years too.
Not something anyone would be likely to ever forget.
There have been several smaller eruptions since then. If you have not seen it, it is a great place to go see what nature is capable of. Unfortunately, all the cabins and such that were destroyed got taken in as part of the volcanic monument that was created, so you can’t really go vacation on the mountain anymore.
