Mount Bird

Template:Infobox mountain Mount Bird () is a high shield volcano standing about south of Cape Bird, the northern extremity of Ross Island. It was mapped by the British National Antarctic Expedition, 1901–04, under Robert Falcon Scott, and apparently named by them after Cape Bird.Template:Sfn

Geography

Mount Bird was originally a separate island, which through volcanic activity has become a rounded peninsula on the northwestern tip of Ross Island. At its southernmost point, where it is connected with the rest of the island by a wide isthmus, a high pass, Bird Pass, separates the bulk of Mount Bird from the northern slopes of Mount Erebus. The peninsula is flanked to the west and east by two large and frequently ice-bound bays, Wohlschlag Bay in the west and Lewis Bay in the east.

Geology

Mount Bird is a basaltic shield volcano that was active from 4.6 to 3.8 million years ago. On the flanks of the volcano there are poorly exposed basalt scoria cones, and phonolite domes and flows. The coastal cliffs display the shield's thick stack of basalt lava flows.Template:Sfn

Glaciers and streams

Several glaciers or meltwater streams flow from the mountain to the sea.

Fitzgerald Stream

. A stream between Fitzgerald Hill and Inclusion Hill on the lower ice-free west slopes of Mount Bird, flowing to McMurdo Sound across McDonald Beach. Explored by the NZGSAE, 1958-59, and named by the NZ-APC for E.B. Fitzgerald, deputy leader of the expedition.Template:Sfn

Shell Glacier

. A western lobe of the Mount Bird icecap. It descends steeply in the valley north of Trachyte Hill and Harrison Bluff in the center of the ice-free area on the lower western slopes of Mount Bird. Mapped and so named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1958–59, because of the marine shell content of the moraines.Template:Sfn

Harrison Stream

. A small stream flowing west between Trachyte and Cinder Hills to the north end of Romanes Beach. Mapped by the NZGSAE, 1958-59. Named by the New Zealand Antarctic Place-Names Committee (NZ-APC) for J. Harrison, mountaineer-assistant with the expedition.Template:Sfn

Wilson Stream

. A meltwater stream which flows from the ice-free lower west slopes of Mount Bird, to the south of Alexander Hill, and over steep sea cliffs into Wohlschlag Bay. Mapped by the NZGSAE, 1958-59, and named by the NZ-APC for J. Wilson, mountaineer assistant with the expedition.Template:Sfn

Quaternary Icefall

. A western lobe of the Mount Bird icecap, descending steeply into Wohlschlag Bay south of Cinder Hill. Mapped and so named by the NZGSAE, 1958-59, because of the Quaternary glacial period marine shells carried by the glacier and deposited in terminal moraines.Template:Sfn

Endeavour Piedmont Glacier

. A piedmont glacier, long and wide, between the southwest part of Mount Bird and Micou Point. In association with the names of expedition ships grouped on this island, named after HMNZS Endeavour, tanker/supply ship which for at least 10 seasons, 1962-63 to 1971-72, transported bulk petroleum products and cargo to Scott Base and McMurdo Station on Ross Island.Template:Sfn
