New Moto Guzzi Door Mats Available Now
I lost Rollonda, my Ambassador to Mt. St. Helens. The short story is that we were camping up there when it blew and three bikes with 4 people left in a hurry. We lost one bike before we got out of the logging roads due to 0 visibility and debris in the roadbed. We collected that rider and made for Olympia, where I was working at the time. We shut down the bikes at the shop -- my ambo and a KZ650 -- and they never ran again. The ash had completely fouled the engines, wheel bearings, cables -- it was everywhere that fine grit could get. Nothing was salvageable. All the air cleaners in the world wouldn't have stopped the damage. I saved the sandblasted headlight for several years, but it's gone now. I was driving tow truck in Olympia when that happened. We were hauling dead vehicles to central dump sites just to clear the freeway. Sometimes we'd open the hoods and they'd fold up from the weight of the ash. We were covering air cleaners and other intake areas on the trucks with oiled foam and pantyhose trying to keep the ash out, but we lost half of the county's tow truck fleet to ash damage.
No, by our maps we were just outside the red zone, on the NW edge, IIRC. Apparently thousands of folks assumed their air cleaners would stop the ash. The problem was that a lot of smaller particles got through some, and others simply plugged as you say. Either way they were dead beside the road until we could drag them off. And a lot of folks thought the air intake of an engine was the only risky place for ash. Immersing a running vehicle in ash or water is really no different as far as the machine's future.
The farmer told me when that happens, the cattle stop eating and come to the barn. The cattle were smarter than the farmer thought.
It drifted like snow through SW and eastern WA for some years afterward. Folks buying machinery had to beware of "ash cars" like we were wary of 'flood bikes' after Money Creek.But the farmers I know swear that as soon as it got down into the dirt their crops liked it real well.
