How and when did Antarctica come to the South Pole? ” but there is ample geologic evidence to indicate that it has not. Sedimentary rocks of Mesozoic age along the Antarctic Peninsula show beautiful fossilized tropical ferns, and Paleozoic-age coal seams in the Transantarctic Mountains reveal well-preserved low-latitude vegetation. No, Antarctica was not always at the South Pole—it came there from somewhere else, and fairly recently, geologically speaking. At the beginning of the Jurassic period, some two hundred million years ago, the terrain that was to become Antarctica was part of a super-continental assemblage called Gondwanaland, an enormous landmass that also comprised the eventual continents of South America, Africa, and Australia, as well as smaller fragments including Madagascar, New Zealand, and India.

Ice has been on Earth much longer than people have—we are relative newcomers to the terrestrial menagerie.

This is truly “the world without us,”4 a frozen part of the Garden of Eden that has been off limits to us for most of human history. The colors of the Antarctic are unlike colors elsewhere. Whereas green is the signature color of well-watered vegetation everywhere, and reds, yellows, and tans paint Earth’s deserts, Antarctica specializes in black, white, and blue.
