Geologist John Goodge looks for clues about Antarctica's past in the two percent of the continent that is not covered in ice! The University of Minnesota, Duluth professor studies rocks that help provide evidence about how this desolate continent has formed and changed over time. He also hopes to get a better idea of what the Earth looked like long before the seven continents we have now. Goodge and his colleagues are supported by the U.S. Antarctic Program, which is managed by the National Science Foundation. In late 2010 and early 2011, he spent several weeks in the field with other scientists, visiting a dozen sites in Antarctica, along 1200 miles of mountains. They collected 2500 pounds of rocks, which are now being analyzed back in the states.
