Electoral and Geologic Boundaries
I’m slowly transitioning out of election mode and back into geoscience mode. To help this transition, this post combines both!
The map below (from this NY Times page) shows the counties that voted more Republican (in shades of red) and the counties that voted more Democratic (in shades of blue) as compared to 2004. There is a very distinct belt of deep red extending from the Appalachians to the Ouachitas in Arkansas and Oklahoma.
Now compare that belt of red to the map below that shows the Appalachian-Ouachita orogenic belt, which reflects the suturing of Gondwana and Laurasia to form Pangea in the mid to late Paleozoic.
Okay, I guess the western Cordilleran belt doesn’t match anything … whatever … I wrote this post in about 2 minutes!
Geology-rich posts are in the works … stay tuned.
UPDATE (11/16/2008): Along the lines of the some of the comments below, I came across this composite map (from the Strange Maps blog) showing the counties that voted for Obama vs. McCain (blue and red colors, respectively) with the dots represent where cotton was produced in 1860 (each dot representing 2,000 bales).
