Geology of Middle Earth

When I was an undergrad, I took a required Geology course.  The professor told me that he was impressed with my passion for maps, and asked whether I might be interested in switching majors.   At the time, I was not.  Little did I know, geologists also make maps of incredible places like Middle Earth and Oz.

Had I known then what I know now, perhaps I would have made a super fast skip and a jump in the change of major.
