So, the large yellow circle is my approximation (guess?) of where Nevada was on Pangaea in the late Triassic.
This post follows on with several other GeoBlogosphere posts, starting with Chris at Goodschist and then several others including Callan at NOVA Geoblog and Brian at Clastic Detritus. You can compare my large, ungainly yellow circle for the approximate location of central Nevada with Brian's small circle for the location of the Bay Area and see that at least they overlap!
Oh, and at least one more geoblogger has joined in - Chris at Highly Allochthonous.
And another one: Hypocentre at Hypo-Thesis.
