A view up the Ferrar Glacier in south Victoria Land, Antarctica. On the right, a dark Jurassic Ferrar dolerite sill intrudes Cambro-Ordovician basement granitic rocks of the Granite Harbor Intrusive suite. The granites formed during the later part of Gondwana's assembly, and the dolerites were intruded early in the breakup of that supercontinent. Peaks in the distance are underlain by the flat-lying Devonian-Triassic Beacon Supergroup, which unconformably overlies the granitic basement along the Kukri Peneplain. Geologists at Byrd Polar are involved in understanding all aspects of the geology shown in this panorama.
