In The Geology of Game of Thrones, a group of geologists has created a geologic map of Westeros and Essos, as well as an invented geologic history of the planet on which George R. R. Martin’s epic takes place. Via io9.
This isn’t the first time a fantasy world has been looked at through a geologic lens. Karen Wynn Fonstad’s Atlas of Middle-earth took a reasonably rigorous look at the landforms of Middle-earth. And Antony Swithin—a geologist in real life under his real name, William Sarjeant—created a geologic map of his invented island of Rockall (see previous entry).
