English: Geikie Plateau glacier and mountain peaks in eastern Greenland seen from NASA's P-3B during an IceBridge survey flight on Apr. 11, 2013. The distinctive layering in the Geikie Plateau's mountains come from repeated flooding of basalt lava from the North Atlantic's mid-ocean ridge millions of years ago.
