Derby Island
Derby Island is a small rocky island close north of Astrolabe [Glacier Tongue], lying southwest of Pasteur Island at the southern end of the Dumoulin Islands. It was photographed from the air by U.S. [Navy Operation Highjump], 1946–47, charted by the French Antarctic Expedition, 1949–51, and so named because French field parties competed against each other for the honor of being first to reach the island area.
