Only about two percent of the Antarctic continent pokes through the ice
cover, but the parts that do are very dramatic. The Transantarctic
Mountains stretch over 3,000 km (over 2,100 miles) through the
continent, dividing East Antarctica from West Antarctica. These dramatic
peaks stick out of the ice and can have incredible vertical rock faces.
The highest mountain in Antarctica is Mount Vinson, at 4,892 meters
(over 16,000 feet) above sea level. It was discovered only in 1958 by a
U.S. Navy aircraft.
