U.S.-led team confirms an Alps-like mountain range exists under east Antarctic ice sheet
 Capstone of NSF-supported International Polar Year

Feb. 25,
2009 --
Flying twin-engine light aircraft the equivalent of three trips around the globe and working in temperatures that averaged minus 30 degrees Celsius, an international team of scientists, including one from Washington University in St. Louis, has not only verified the existence of a mountain range that is suspected to have caused the massive East Antarctic Ice Sheet to form, but also has created a detailed picture of the rugged landscape buried under more than four kilometers (2.5 miles) of ice.
