The geology of Game of Thrones

Image Map

This is Westeros as it exists in the days of tumult, in the days following the death of King Robert Baratheon, in the shortening days that warn that winter is coming.  But this is also the geologic history of Westeros, reaching far deeper through the annals of time than the reign of any of the Seven Kingdoms.  We pieced this geologic history together from character observations, town names, official Game of Thrones maps, and the principles of geology learned here on Earth.  Using only limited data we were able to reimagine 500 million years of planetary evolution, including volcanoes, continents rising from the oceans, and ice ages (with guest appearance by white walkers and dragons).  To explore the history, and to view our maps of the geologic reconstructions, click the numbered icons on the map, or on the links below.

Geologic events occurring XX million years ago (Mya) on Westeros:
(today) The size of the Game of Thrones planet
(25 Mya) The Earth split Westeros from Essos
(30-40 Mya) When Dorne boiled
(40 Mya) Land of ice
(60-80 Mya) The rise of the Black Mountains
(80-100 Mya) As the Moon rose, so did the Lannisters
(300 Mya) Diving the tropical reefs of Winterfell
(450 Mya) The sand ran red
(500 Mya) The first mountains
(2,000 Mya) Can you find it?
