Antarctica is a fascinating place. I was thinking about the post-war status of the mysterious continent at the bottom of the world, and then I realized that we actually do have a lot of evidence as to what happened to it. THE FACTS: Penguins are extinct, according to the Fallout Bible 5. The United States liked to put bases in odd places before the War. The vague intro of Fallout 2 insists that "[whole] continents were swallowed in flames and fell beneath the boiling oceans". We heard some word of active fault lines in the original Vault 13 timeline. SPECULATION: The reason for the extinction of Penguins, referred to in the Fallout Bible, is actually due to concentrated nuclear attacks on American, Chinese and Soviet bases on the continent. As the world buckled under the pressure of the war, the stress of the fault lines in Antarctica perhaps caused a series of earthquakes that formed a rift in the continent? Due to intense environmental changes across the planet, Antarctica is starting to melt. What are your thoughts? Was Antarctica home to anything important before the war? What do you think happened to it after the war? The way Chris described things it sounds like it's even more uninhabitable than before.
