I’m in Silicon Valley — sure don’t remember any ashfall here. You sure it hit SJ? I thought the plume all went east.

I lived in Nampa, ID at the time, east and south of Mt. St. Helens, and I don't remember any ash from it, either. The map in this link may explain why. It appears that it went just north of us heading east, before expanding out and going south. Nampa, ID is on I-84 about 30 miles southeast of the ID/OR border, or on the linked map, just south of the ash plume area.

Just asked my folks, we got trace amounts in our area - a light dusting at most. Which probably explains why I don’t remember any.
