Mount Murphy
Mount Murphy (75°20′S 110°44′W / 75.333°S 110.733°W) is a snow-covered mountain with steep, rocky slopes rising to 2,634 metres (8,642 ft) in Marie Byrd Land, Antarctica. It is directly south of Bear Peninsula and is bounded by Smith Glacier, Pope Glacier, and Haynes Glacier. Volcanic activity began in the Miocene with the eruption of basaltic and trachytic lava. Volcanism on the slopes of the volcano resumed much later during the Pleistocene, with a parasitic cone having been K–Ar dated to 0.9 million years old.
The Mount Murphy massif lies on the south shore of the Crosson Ice Shelf, which extends into the Amundsen Sea on the Walgreen Coast of Marie Byrd Land. The Haynes Glacier flows into the ice shelf to its east, and the Pope Glacier flows into the ice shelf to the west. The Roos Glacier and Vane Glacier flow from the massif towards the ice shelf. Features, clockwise from the northwest, include Kay Peak, Buettner Peak, Grew Peak, Benedict Peak, Eisberg Head, Callender Peak, Boyd Head, Hawkins Peak, Bucher Peak, Sechrist Peak, Dorrel Rock, Turtle Peak, Hedin Nunatak.
Mount Murphy was delineated from aerial photographs taken by United States Navy Operation Highjump in January 1947. It was named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Robert Cushman Murphy of the American Museum of Natural History, noted authority on Antarctic and sub-Antarctic bird life. While serving on the whaler, he charted the Bay of Isles region of South Georgia.
75°25′S 109°30′W / 75.417°S 109.500°W. A broad glacier flowing to Walgreen Coast, to the east of Mount Murphy. Mapped by the United States Geological Survey (USGS) from surveys and United States Navy air photos, 1959–66. Named by US-ACAN after Major John W. Haynes, USMC, aircraft pilot on Operation Deep Freeze 1967 and 1968, who made a photographic flight over this glacier on January 1, 1967.
75°19′S 111°22′W / 75.317°S 111.367°W. A glacier about 20 nautical miles (37 km; 23 mi) long, flowing north along the west side of Mount Murphy to Crosson Ice Shelf. Mapped by USGS from surveys and United States Navy air photos, 1959–66. Named by US-ACAN after Major Donald R. Pope, (CE) United States Army, civil engineer on the staff of the Commander, Naval Support Force, Antarctica, 1965–67.
75°17′S 110°57′W / 75.283°S 110.950°W. A steep glacier that drains the northwest slopes of Mount Murphy. Named by US-ACAN after S. Edward Roos, oceanographer with the Byrd Antarctic Expeditions of 1928-30 and 1933–35.
75°15′S 110°19′W / 75.250°S 110.317°W. A broad glacier that drains the northeast slopes of Mount Murphy. It enters Crosson Ice Shelf between Eisberg Head and Boyd Head. Mapped by USGS from surveys and United States Navy air photos, 1959–66. Named by US-ACAN for Gregg A. Vane, United States Exchange Scientist at the Soviet station Novolazerevskaya in 1972.
75°14′S 110°57′W / 75.233°S 110.950°W. A pyramidal peak, 760 metres (2,490 ft) high, near the end of the large spur descending northwest from the Mount Murphy massif. Mapped by USGS from surveys and United States Navy air photos, 1959–66. Named by US-ACAN for Lieutenant Commander W. Kay, United States Navy, leader of the Construction Unit at South Pole Station during Operation Deep Freeze 1973.
