I'm very new to this too. Actually, I don't for sure that the tones I've been getting don't include Yellowstone, also.
BTW, I had a very vivid dream a few years ago of 2 volcanoes erupting at the same time. There was also a comet in the sky.
I felt compelled to make a painting of this dream. I lost the painting when I moved, but I still have a picture of it.
