From the Lewis Cliff ice tongue, Antarctica, where more than 1900 meteorite stones have been collected, including LEW88516, a Martian meteorite (lherzolitic shergottite).
In the foreground are rocks of "meteorite moraine." The prominent dark feature in the center background is Coalsack Bluff in the Transantarctic Mountains, where the first Antarctic Lystrosaurus fossil was discovered in 1969-70 by Edwin H. Colbert and his team. Lystrosaurus is found in the lower Triassic of southern Africa as well as in India and China. The Antarctic discovery of Lystrosaurus was one of the last and most compelling arguments to sway opponents of the theory of "continental drift." Randy Korotev took the photo in 1989 while searching for meteorites as part of the ANSMET program. If the image looks familiar, it's because the mural over the E&PS library is based on the photo.
