The Victory Mountains (72°40′S 168°00′E / 72.667°S 168.000°E / -72.667; 168.000 (Victory Mountains)) is a major group of mountains in Victoria Land, Antarctica, about 100 nautical miles (190 km; 120 mi) long and 50 nautical miles (93 km; 58 mi) wide, which is bounded primarily by Mariner and Tucker glaciers and the Ross Sea.^[1] They are north of the Mountaineer Range, east of the Freyberg Mountains and south of the Concord Mountains and the Admiralty Mountains.^[2][3][4][5] The division between the Victory Mountains and the Concord Mountains (to the northwest) is not precise but apparently lies in the vicinity of Thomson Peak.^[1]

Exploration and name

A Ross Sea aspect of the mountains was first obtained by early British expeditions of James Clark Ross, Carsten Borchgrevink, Robert Falcon Scott and Ernest Shackleton. The mapping of the interior mountains was largely done from air photos taken by the United States Navy and surveys undertaken by New Zealand and American parties in the 1950s and 1960s. The Victory Mountains were named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE) 1957-58, because of the proximity of this group to the Admiralty Mountains, and with the intention that many of the topographic features would be named for celebrated victories, especially naval victories.^[1]

Location

Western mountains

The Monteath Hills are in the northwest of the Victory Mountains, east of the Freyberg Mountains. The Millen Range and Barker Range are to their south, east of the Evans Névé and the smaller Webb Névé. The Mariner Glacier forms to the west of the Barker Range and flows south and then east, separating the Victory Mountains from the Mountaineer Range.^[2][3][4][5]

Central mountains

The Saxby Range is to the west of the Monteath Hills, between Midway Glacier to the west, Pearl Harbor Glacier to the south and Tucker Glacier to the east, which flows to the southeast and separates the Victory Mountains from the Admiralty Mountains. The Cartographers Range is south of the Pearl Harbor Glacier and north of the Trafalgar Glacier. The Malta Plateau is to the south of the Trafalger Glacier and north of the Mariner Glacier.^[2][3][4][5]

Eastern mountains

The mountains to the east of the Malta Plateau and west of the Daniell Peninsula are not part of a formally named range. Mount Riddolls is at the center of a ridge system to the east of Borchgrevink Glacier, and Mount Freeman is at the center of a ridge system to the west of that glacier.^[2][3][4][5]

• Tucker Glacier 72°32′S 169°15′E / 72.533°S 169.250°E / -72.533; 169.250 (Tucker Glacier), a major valley glacier, about 90 nautical miles (170 km; 100 mi) long, flowing southeast between the Admiralty Mountains and the Victory Mountains to the Ross Sea. There is a snow saddle at the glacier's head, just west of Homerun Range, from which the Ebbe Glacier flows northwestward.^[6]
• Pearl Harbor Glacier 72°15′S 167°40′E / 72.250°S 167.667°E / -72.250; 167.667, a major tributary glacier flowing generally east from the Victory Mountains and entering the southwest side of Tucker Glacier 17 nautical miles (31 km; 20 mi) northwest of Bypass Hill.^[7]
• Trafalgar Glacier 72°28′S 168°25′E / 72.467°S 168.417°E / -72.467; 168.417, a tributary glacier about 30 nautical miles (56 km; 35 mi) long, flowing east in the Victory Mountains to join Tucker Glacier below Bypass Hill.^[8]
• Borchgrevink Glacier 73°4′S 168°30′E / 73.067°S 168.500°E / -73.067; 168.500 (Borchgrevink Glacier), a large glacier in the Victory Mountains. It drains south between Malta Plateau and Daniell Peninsula, and thence projects into Glacier Strait, Ross Sea, as a floating glacier tongue.^[9]
• Mariner Glacier 73°15′S 167°30′E / 73.250°S 167.500°E / -73.250; 167.500 (Mariner Glacier), a major glacier over 60 nautical miles (110 km; 69 mi) long, descending southeast from the plateau of Victoria Land, between Mountaineer Range and Malta Plateau, and terminating at Lady Newnes Bay, Ross Sea, where it forms the floating Mariner Glacier Tongue.^[10]
