Many thanks, Lisa, for the references you gave for the Yellowstone Hot Spot! Question 1: Are any on the Web with open access? You mentioned some PDF files. I am fascinated by the findings lying beneath Yellowstone Lake. Question 2: Robert Smith gave a lecture on the Yellowstone Plume this last summer at the Salt Lake City Public Library. He showed a recent computer graphic of the plume underlying Yellowstone (made from seismic studies). I was awe struck by the plumes size! He rotated it to give the audience a perspective of what it looked like --- very irregular and extending VERY deep, like an elongated potato, down into the earth. I would also LOVE to get my hands on this visual! Is there anything on the Web, that you know about, showing this visual? I do remember that if you picture a baseball and place a postage stamp on it, the baseball would roughly represent the size of the plume ... the postage stamp would represent the present boundaries of Yellowstone.
