Indeed. Yellowstone has been about to erupt for a zillion years.
Of course, if it does, my daughter and SIL in N. ID will be in its path and I might too in Spokane. Gotta go some way. It’s in God’s hands. And so are we.
Actually, corrected figures for mega-eruptions are 2.1M, 1.2M, and 640,000 years ago. Below is a map showing the ask spread of two of the major Yellowstone blows, and the Long Valley one that occurred in the 800K to 700,000 ago period. Mostly the ash blows east, and these maps don’t show N. ID or Spokane in the likely path for heavy fall. For more images, Google “Images of Yellowstone mega-volcano ash dispersal maps”
