Location
The Crosson Ice Shelf extends northeast into the Amundsen Sea on the Walgreen Coast of Marie Byrd Land. The Bear Peninsula is on its northwest. The Mount Murphy massif is along its south edge. [2] [3]
The Crosson Ice Shelf ( 74°57′S109°30′W / 74.950°S 109.500°W ) is an ice shelf, about 35 nautical miles (65 km; 40 mi) wide, located north and northeast of Mount Murphy along the Walgreen Coast of Marie Byrd Land, Antarctica. The ice shelf is nurtured by Smith Glacier, Pope Glacier, Vane Glacier, and Haynes Glacier. [1]

Crosson Ice Shelf was mapped by the United States Geological Survey (USGS) from surveys and from United States Navy air photographs, 1959–66. It was named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Commander W.E. Crosson, U.S. Navy, Commanding Officer of the Antarctic Construction Group during Operation Deep Freeze 1973. [1]
Thurston Island is a largely ice-covered, glacially dissected island, 135 nautical miles long and 55 nautical miles wide, lying between between Amundsen Sea and Bellingshausen Sea a short way off the northwest end of Ellsworth Land, Antarctica. The island is separated from the mainland by Peacock Sound, which is occupied by the west portion of Abbot Ice Shelf.
The Britannia Range is a range of mountains bounded by the Hatherton Glacier and Darwin Glacier on the north and the Byrd Glacier on the south, westward of the Ross Ice Shelf in Antarctica.
The Scaife Mountains is a group of mountains rising west of Prehn Peninsula and between the Ketchum Glacier and Ueda Glacier, at the base of the Antarctic Peninsula.
The Abbot Ice Shelf is an ice shelf 250 nautical miles long and 40 nautical miles wide, bordering Eights Coast from Cape Waite to Pfrogner Point in Antarctica. Thurston Island lies along the northern edge of the western half of this ice shelf; other sizable islands lie partly or wholly within this shelf.
Mount Murphy is a massive, snow-covered mountain with steep, rocky slopes rising to 2,505 metres (8,219 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.
Kohler Range is a mountain range in Marie Byrd Land, Antarctica. The range is about 40 nautical miles long and stands between the base of Martin Peninsula and Smith Glacier. The range consists of two ice-covered plateaus punctuated by several rock peaks and bluffs. The plateaus are oriented East-West and are separated by the Kohler Glacier, a distributary which flows north from Smith Glacier.
Dotson Ice Shelf is an ice shelf about 30 miles (50 km) wide between Martin Peninsula and Bear Peninsula on the coast of Marie Byrd Land in Antarctica. It was first mapped by the U.S. Geological Survey from air photos obtained by U.S. Navy Operation Highjump in January 1947, and was named by the Advisory Committee on Antarctic Names for Lieutenant William A. Dotson, US Navy, formerly Officer in Charge of the Ice Reconnaissance Unit of the Naval Oceanographic Office, killed in a plane crash in Alaska in November 1964 while on an ice reconnaissance mission.
Smith Glacier (75°05′S112°00′W is a low-gradient Antarctic glacier, over 160 km long, draining from Toney Mountain in an ENE direction to Amundsen Sea. A northern distributary, Kohler Glacier, drains to Dotson Ice Shelf but the main flow passes to the sea between Bear Peninsula and Mount Murphy, terminating at Crosson Ice Shelf.
Bear Peninsula is a peninsula about 50 nautical miles long and 25 nautical miles wide which is ice-covered except for several isolated rock bluffs and outcrops along its margins, lying 3 nautical miles east of Martin Peninsula on Walgreen Coast, Marie Byrd Land, Antarctica.
Martin Peninsula is a peninsula about 60 nautical miles long and 20 nautical miles wide that is ice-covered except for a few rock outcrops along its margins, located between Getz Ice Shelf and Dotson Ice Shelf on the coast of Marie Byrd Land, Antarctica. The farthest point of the peninsula is Jacobsen Head.
Sulzberger Bay is a bay indenting the front of the Sulzberger Ice Shelf between Fisher Island and Vollmer Island, along the coast of Marie Byrd Land, Antarctica.
Sulzberger Ice Shelf is an ice shelf about 85 nautical miles long and 50 nautical miles wide bordering the coast of Marie Byrd Land between Edward VII Peninsula and Guest Peninsula in Antarctica.
The Mulock Glacier is a large, heavily crevassed glacier which flows into the Ross Ice Shelf 40 kilometers south of the Skelton Glacier in the Ross Dependency, Antarctica.
The Bender Mountains are a small group of mountains 4 nautical miles southwest of the Berry Peaks, between the southeast edge of the Ross Ice Shelf and the Watson Escarpment.
Bowyer Butte is a steep-cliffed eminence with a nearly flat summit, 3 nautical miles wide and 1,085 metres (3,560 ft) high, located between the lower ends of the Johnson Glacier and the Venzke Glacier on the coast of Marie Byrd Land, Antarctica.
Nicholson Peninsula is a broad ice-covered peninsula about 15 nautical miles (28 km) long, between Couzens Bay and Matterson Inlet on the Shackleton Coast on the west side of the Ross Ice Shelf, Antarctica.
Strom Glacier is a steep valley glacier flowing northeast from the north side of Mount Fridtjof Nansen to the head of the Ross Ice Shelf, flanked on the northwest by the Duncan Mountains and on the southeast by the Herbert Range.
The Playfair Mountains are a group of mountains between Swann Glacier and Squires Glacier in southeast Palmer Land, Antarctica.
Pope Glacier is a glacier about 20 nautical miles (37 km) long, flowing north along the west side of Mount Murphy to Crosson Ice Shelf on Walgreen Coast, in Marie Byrd Land. Mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1959–66. Named by Advisory Committee on Antarctic Names (US-ACAN) after Maj. Donald R. Pope, (CE) USA, civil engineer on the staff of the Commander, Naval Support Force, Antarctica, 1965–67. It is a tributary of Smith Glacier.
Hull Bay is an ice-filled bay, about 25 nautical miles wide, fed by Hull Glacier, which descends into it between Lynch Point and Cape Burks, on the coast of Marie Byrd Land, Antarctica.
