Antarctica is a land of extremes: it is the coldest and driest continent on Earth and has the highest average elevation. As the fifth largest continent in the world, Antartica is also the most Southern, overlying the "South Pole". Scarcely touched by humans, the frozen land boasts breathtaking scenery, broken by only handful of scientific bases and a "permanent" population of scientists numbering only a few thousand. Visitors to Antarctica generally must brave rough sea crossings aboard ice-strengthened vessels, but those who do are rewarded with amazing scenery and tremendous and unique wildlife.
