Quite an event. I lived in Yakima at the time. Had an inch or more on my roof. I set plastic sheets out on my lawn to collect ash. When it stopped, I couldn't even pull up the sheets because of all the weight. I kept several buckets of the stuff and used it to weight the back-end of my pickup when roads were icy. It sure helped to throrw a few handfuls of ash on the ice to get you going.
I flew some NBC? news crews into the crater to report on the dome that was forming but it basiclly was a non-event . I also slow hovered over many acres of corn and hops to blow the ash off, It turned out to be a good thing, I heard that the wheat farmers had a bumper crop,
