2.1 million years ago was more than twice as strong, leaving a hole in the ground the size of Rhode Island."
These sentences are taken from an article entitled "When Yellowstone Explodes" (pg. 56-69, National Geographic, August 2009), by Joel Achenbach. Over the years, I've seen this reference, "the size of Rhode Island," hundreds of times in print and I have heard it probably just as many. I'd like to use this blog space as an ongoing record, starting now, of these references, and I invite you to participate. Please try to place the reference in as accurate a context as possible, citing the source if you can.
This information will be used for a future class project.
