McMurdo Sound is the southernmost body of ocean water in the world. Bordered by the trans-antarctic mountains on one side and Ross Island and the Ross Ice shelf on the other, its southern shore is near 78 degrees south. McMurdo Station is located on Ross Island at the southern shore. McMurdo Station is the largest base in the Antarctic, and supports Scott-Amundsen station at the South Pole, and all the smaller field camps and science groups across the continent. The scenery is dominated by the 12500 ft volcano, Mount Erebus, and the 14000 ft Royal Society Range across the sound. Parts of the Ross Ice shelf, and McMurdo Sound are the setting for these massive features, the sunrises and sunsets light the ice and mountains creating unearthly beauty.
